# 1.0.0[−][src]Struct std::path::PathBuf

    pub struct PathBuf { /* fields omitted */ }

An owned, mutable path (akin to `String`).

This type provides methods like `push` and `set_extension` that mutate the path in place. It also implements `Deref` to `Path`, meaning that all methods on `Path` slices are available on `PathBuf` values as well.

More details about the overall approach can be found in the module documentation.

# Examples

You can use `push` to build up a `PathBuf` from components:

    use std::path::PathBuf;

    let mut path = PathBuf::new();

    path.push(r"C:\");
    path.push("windows");
    path.push("system32");

    path.set_extension("dll");

Run

However, `push` is best used for dynamic situations. This is a better way to do this when you know all of the components ahead of time:

    use std::path::PathBuf;

    let path: PathBuf = [r"C:\", "windows", "system32.dll"].iter().collect();

Run

We can still do better than this! Since these are all strings, we can use `From::from`:

    use std::path::PathBuf;

    let path = PathBuf::from(r"C:\windows\system32.dll");

Run

Which method works best depends on what kind of situation you're in.

## Methods

### `impl PathBuf`[src]

#### `pub fn new() -> PathBuf`[src]

Allocates an empty `PathBuf`.

# Examples

    use std::path::PathBuf;

    let path = PathBuf::new();

Run

#### `pub fn with_capacity(capacity: usize) -> PathBuf`[src]

🔬 This is a nightly-only experimental API. (`path_buf_capacity` #58234)

Creates a new `PathBuf` with a given capacity used to create the internal `OsString`. See `with_capacity` defined on `OsString`.

# Examples

    #![feature(path_buf_capacity)]
    use std::path::PathBuf;

    let mut path = PathBuf::with_capacity(10);
    let capacity = path.capacity();

    // This push is done without reallocating
    path.push(r"C:\");

    assert_eq!(capacity, path.capacity());

Run

#### `pub fn as_path(&self) -> &Path`[src]

Coerces to a `Path` slice.

# Examples

    use std::path::{Path, PathBuf};

    let p = PathBuf::from("/test");
    assert_eq!(Path::new("/test"), p.as_path());

Run

#### `pub fn push<P: AsRef<Path>>(&mut self, path: P)`[src]

Extends `self` with `path`.

If `path` is absolute, it replaces the current path.

On Windows:

- if `path` has a root but no prefix (e.g., `\windows`), it replaces everything except for the prefix (if any) of `self`.
- if `path` has a prefix but no root, it replaces `self`.

# Examples

Pushing a relative path extends the existing path:

    use std::path::PathBuf;

    let mut path = PathBuf::from("/tmp");
    path.push("file.bk");
    assert_eq!(path, PathBuf::from("/tmp/file.bk"));

Run

Pushing an absolute path replaces the existing path:

    use std::path::PathBuf;

    let mut path = PathBuf::from("/tmp");
    path.push("/etc");
    assert_eq!(path, PathBuf::from("/etc"));

Run

#### `pub fn pop(&mut self) -> bool`[src]

Truncates `self` to `self.parent`.

Returns `false` and does nothing if `self.parent` is `None`. Otherwise, returns `true`.

# Examples

    use std::path::{Path, PathBuf};

    let mut p = PathBuf::from("/test/test.rs");

    p.pop();
    assert_eq!(Path::new("/test"), p);
    p.pop();
    assert_eq!(Path::new("/"), p);

Run

#### `pub fn set_file_name<S: AsRef<OsStr>>(&mut self, file_name: S)`[src]

Updates `self.file_name` to `file_name`.

If `self.file_name` was `None`, this is equivalent to pushing `file_name`.

Otherwise it is equivalent to calling `pop` and then pushing `file_name`. The new path will be a sibling of the original path. (That is, it will have the same parent.)

# Examples

    use std::path::PathBuf;

    let mut buf = PathBuf::from("/");
    assert!(buf.file_name() == None);
    buf.set_file_name("bar");
    assert!(buf == PathBuf::from("/bar"));
    assert!(buf.file_name().is_some());
    buf.set_file_name("baz.txt");
    assert!(buf == PathBuf::from("/baz.txt"));

Run

#### `pub fn set_extension<S: AsRef<OsStr>>(&mut self, extension: S) -> bool`[src]

Updates `self.extension` to `extension`.

Returns `false` and does nothing if `self.file_name` is `None`, returns `true` and updates the extension otherwise.

If `self.extension` is `None`, the extension is added; otherwise it is replaced.

# Examples

    use std::path::{Path, PathBuf};

    let mut p = PathBuf::from("/feel/the");

    p.set_extension("force");
    assert_eq!(Path::new("/feel/the.force"), p.as_path());

    p.set_extension("dark_side");
    assert_eq!(Path::new("/feel/the.dark_side"), p.as_path());

Run

#### `pub fn into_os_string(self) -> OsString`[src]

Consumes the `PathBuf`, yielding its internal `OsString` storage.

# Examples

    use std::path::PathBuf;

    let p = PathBuf::from("/the/head");
    let os_str = p.into_os_string();

Run

#### `pub fn into_boxed_path(self) -> Box<Path>`1.20.0[src]

Converts this `PathBuf` into a boxed `Path`.

#### `pub fn capacity(&self) -> usize`[src]

🔬 This is a nightly-only experimental API. (`path_buf_capacity` #58234)

Invokes `capacity` on the underlying instance of `OsString`.

#### `pub fn clear(&mut self)`[src]

🔬 This is a nightly-only experimental API. (`path_buf_capacity` #58234)

Invokes `clear` on the underlying instance of `OsString`.

#### `pub fn reserve(&mut self, additional: usize)`[src]

🔬 This is a nightly-only experimental API. (`path_buf_capacity` #58234)

Invokes `reserve` on the underlying instance of `OsString`.

#### `pub fn reserve_exact(&mut self, additional: usize)`[src]

🔬 This is a nightly-only experimental API. (`path_buf_capacity` #58234)

Invokes `reserve_exact` on the underlying instance of `OsString`.

#### `pub fn shrink_to_fit(&mut self)`[src]

🔬 This is a nightly-only experimental API. (`path_buf_capacity` #58234)

Invokes `shrink_to_fit` on the underlying instance of `OsString`.

#### `pub fn shrink_to(&mut self, min_capacity: usize)`[src]

🔬 This is a nightly-only experimental API. (`path_buf_capacity` #58234)

Invokes `shrink_to` on the underlying instance of `OsString`.

## Methods from Deref<Target = Path>

#### `pub fn as_os_str(&self) -> &OsStr`[src]

Yields the underlying `OsStr` slice.

# Examples

    use std::path::Path;

    let os_str = Path::new("foo.txt").as_os_str();
    assert_eq!(os_str, std::ffi::OsStr::new("foo.txt"));

Run

#### `pub fn to_str(&self) -> Option<&str>`[src]

Yields a `&str` slice if the `Path` is valid unicode.

This conversion may entail doing a check for UTF-8 validity. Note that validation is performed because non-UTF-8 strings are perfectly valid for some OS.

# Examples

    use std::path::Path;

    let path = Path::new("foo.txt");
    assert_eq!(path.to_str(), Some("foo.txt"));

Run

#### `pub fn to_string_lossy(&self) -> Cow<str>`[src]

Converts a `Path` to a `Cow<str>`.

Any non-Unicode sequences are replaced with `U+FFFD REPLACEMENT CHARACTER`.

# Examples

Calling `to_string_lossy` on a `Path` with valid unicode:

    use std::path::Path;

    let path = Path::new("foo.txt");
    assert_eq!(path.to_string_lossy(), "foo.txt");

Run

Had `path` contained invalid unicode, the `to_string_lossy` call might have returned `"fo�.txt"`.

#### `pub fn to_path_buf(&self) -> PathBuf`[src]

Converts a `Path` to an owned `PathBuf`.

# Examples

    use std::path::Path;

    let path_buf = Path::new("foo.txt").to_path_buf();
    assert_eq!(path_buf, std::path::PathBuf::from("foo.txt"));

Run

#### `pub fn is_absolute(&self) -> bool`[src]

Returns `true` if the `Path` is absolute, i.e., if it is independent of the current directory.

- On Unix, a path is absolute if it starts with the root, so `is_absolute` and `has_root` are equivalent.

- On Windows, a path is absolute if it has a prefix and starts with the root: `c:\windows` is absolute, while `c:temp` and `\temp` are not.

# Examples

    use std::path::Path;

    assert!(!Path::new("foo.txt").is_absolute());

Run

#### `pub fn is_relative(&self) -> bool`[src]

Returns `true` if the `Path` is relative, i.e., not absolute.

See `is_absolute`'s documentation for more details.

# Examples

    use std::path::Path;

    assert!(Path::new("foo.txt").is_relative());

Run

#### `pub fn has_root(&self) -> bool`[src]

Returns `true` if the `Path` has a root.

- On Unix, a path has a root if it begins with `/`.

- On Windows, a path has a root if it:

  - has no prefix and begins with a separator, e.g., `\windows`
  - has a prefix followed by a separator, e.g., `c:\windows` but not `c:windows`
  - has any non-disk prefix, e.g., `\\server\share`

# Examples

    use std::path::Path;

    assert!(Path::new("/etc/passwd").has_root());

Run

#### `pub fn parent(&self) -> Option<&Path>`[src]

Returns the `Path` without its final component, if there is one.

Returns `None` if the path terminates in a root or prefix.

# Examples

    use std::path::Path;

    let path = Path::new("/foo/bar");
    let parent = path.parent().unwrap();
    assert_eq!(parent, Path::new("/foo"));

    let grand_parent = parent.parent().unwrap();
    assert_eq!(grand_parent, Path::new("/"));
    assert_eq!(grand_parent.parent(), None);

Run

#### `pub fn ancestors(&self) -> Ancestors` 1.28.0[src]

Produces an iterator over `Path` and its ancestors.

The iterator will yield the `Path` that is returned if the `parent` method is used zero or more times. That means, the iterator will yield `&self`, `&self.parent().unwrap()`, `&self.parent().unwrap().parent().unwrap()` and so on. If the `parent` method returns `None`, the iterator will do likewise. The iterator will always yield at least one value, namely `&self`.

# Examples

    use std::path::Path;

    let mut ancestors = Path::new("/foo/bar").ancestors();
    assert_eq!(ancestors.next(), Some(Path::new("/foo/bar")));
    assert_eq!(ancestors.next(), Some(Path::new("/foo")));
    assert_eq!(ancestors.next(), Some(Path::new("/")));
    assert_eq!(ancestors.next(), None);

Run

#### `pub fn file_name(&self) -> Option<&OsStr>`[src]

Returns the final component of the `Path`, if there is one.

If the path is a normal file, this is the file name. If it's the path of a directory, this is the directory name.

Returns `None` if the path terminates in `..`.

# Examples

    use std::path::Path;
    use std::ffi::OsStr;

    assert_eq!(Some(OsStr::new("bin")), Path::new("/usr/bin/").file_name());
    assert_eq!(Some(OsStr::new("foo.txt")), Path::new("tmp/foo.txt").file_name());
    assert_eq!(Some(OsStr::new("foo.txt")), Path::new("foo.txt/.").file_name());
    assert_eq!(Some(OsStr::new("foo.txt")), Path::new("foo.txt/.//").file_name());
    assert_eq!(None, Path::new("foo.txt/..").file_name());
    assert_eq!(None, Path::new("/").file_name());

Run

#### `pub fn strip_prefix<P>(&self, base: P) -> Result<&Path, StripPrefixError> where
P: AsRef<Path>,` 1.7.0[src]

Returns a path that, when joined onto `base`, yields `self`.

# Errors

If `base` is not a prefix of `self` (i.e., `starts_with` returns `false`), returns `Err`.

# Examples

    use std::path::{Path, PathBuf};

    let path = Path::new("/test/haha/foo.txt");

    assert_eq!(path.strip_prefix("/"), Ok(Path::new("test/haha/foo.txt")));
    assert_eq!(path.strip_prefix("/test"), Ok(Path::new("haha/foo.txt")));
    assert_eq!(path.strip_prefix("/test/"), Ok(Path::new("haha/foo.txt")));
    assert_eq!(path.strip_prefix("/test/haha/foo.txt"), Ok(Path::new("")));
    assert_eq!(path.strip_prefix("/test/haha/foo.txt/"), Ok(Path::new("")));
    assert_eq!(path.strip_prefix("test").is_ok(), false);
    assert_eq!(path.strip_prefix("/haha").is_ok(), false);

    let prefix = PathBuf::from("/test/");
    assert_eq!(path.strip_prefix(prefix), Ok(Path::new("haha/foo.txt")));

Run

#### `pub fn starts_with<P: AsRef<Path>>(&self, base: P) -> bool`[src]

Determines whether `base` is a prefix of `self`.

Only considers whole path components to match.

# Examples

    use std::path::Path;

    let path = Path::new("/etc/passwd");

    assert!(path.starts_with("/etc"));
    assert!(path.starts_with("/etc/"));
    assert!(path.starts_with("/etc/passwd"));
    assert!(path.starts_with("/etc/passwd/"));

    assert!(!path.starts_with("/e"));

Run

#### `pub fn ends_with<P: AsRef<Path>>(&self, child: P) -> bool`[src]

Determines whether `child` is a suffix of `self`.

Only considers whole path components to match.

# Examples

    use std::path::Path;

    let path = Path::new("/etc/passwd");

    assert!(path.ends_with("passwd"));

Run

#### `pub fn file_stem(&self) -> Option<&OsStr>`[src]

Extracts the stem (non-extension) portion of `self.file_name`.

The stem is:

- `None`, if there is no file name;
- The entire file name if there is no embedded `.`;
- The entire file name if the file name begins with `.` and has no other `.`s within;
- Otherwise, the portion of the file name before the final `.`

# Examples

    use std::path::Path;

    let path = Path::new("foo.rs");

    assert_eq!("foo", path.file_stem().unwrap());

Run

#### `pub fn extension(&self) -> Option<&OsStr>`[src]

Extracts the extension of `self.file_name`, if possible.

The extension is:

- `None`, if there is no file name;
- `None`, if there is no embedded `.`;
- `None`, if the file name begins with `.` and has no other `.`s within;
- Otherwise, the portion of the file name after the final `.`

# Examples

    use std::path::Path;

    let path = Path::new("foo.rs");

    assert_eq!("rs", path.extension().unwrap());

Run

#### `#[must_use] pub fn join<P: AsRef<Path>>(&self, path: P) -> PathBuf`[src]

Creates an owned `PathBuf` with `path` adjoined to `self`.

See `PathBuf::push` for more details on what it means to adjoin a path.

# Examples

    use std::path::{Path, PathBuf};

    assert_eq!(Path::new("/etc").join("passwd"), PathBuf::from("/etc/passwd"));

Run

#### `pub fn with_file_name<S: AsRef<OsStr>>(&self, file_name: S) -> PathBuf`[src]

Creates an owned `PathBuf` like `self` but with the given file name.

See `PathBuf::set_file_name` for more details.

# Examples

    use std::path::{Path, PathBuf};

    let path = Path::new("/tmp/foo.txt");
    assert_eq!(path.with_file_name("bar.txt"), PathBuf::from("/tmp/bar.txt"));

    let path = Path::new("/tmp");
    assert_eq!(path.with_file_name("var"), PathBuf::from("/var"));

Run

#### `pub fn with_extension<S: AsRef<OsStr>>(&self, extension: S) -> PathBuf`[src]

# Examples

    use std::path::{Path, PathBuf};

    let path = Path::new("foo.rs");
    assert_eq!(path.with_extension("txt"), PathBuf::from("foo.txt"));

Run

#### `pub fn components(&self) -> Components`[src]

Produces an iterator over the `Component`s of the path.

When parsing the path, there is a small amount of normalization:

- Repeated separators are ignored, so `a/b` and `a//b` both have `a` and `b` as components.

- Occurrences of `.` are normalized away, except if they are at the beginning of the path. For example, `a/./b`, `a/b/`, `a/b/.` and `a/b` all have `a` and `b` as components, but `./a/b` starts with an additional `CurDir` component.

- A trailing slash is normalized away, `/a/b` and `/a/b/` are equivalent.

Note that no other normalization takes place; in particular, `a/c` and `a/b/../c` are distinct, to account for the possibility that `b` is a symbolic link (so its parent isn't `a`).

# Examples

    use std::path::{Path, Component};
    use std::ffi::OsStr;

    let mut components = Path::new("/tmp/foo.txt").components();

    assert_eq!(components.next(), Some(Component::RootDir));
    assert_eq!(components.next(), Some(Component::Normal(OsStr::new("tmp"))));
    assert_eq!(components.next(), Some(Component::Normal(OsStr::new("foo.txt"))));
    assert_eq!(components.next(), None)

Run

#### `pub fn iter(&self) -> Iter`[src]

Produces an iterator over the path's components viewed as `OsStr` slices.

For more information about the particulars of how the path is separated into components, see `components`.

# Examples

    use std::path::{self, Path};
    use std::ffi::OsStr;

    let mut it = Path::new("/tmp/foo.txt").iter();
    assert_eq!(it.next(), Some(OsStr::new(&path::MAIN_SEPARATOR.to_string())));
    assert_eq!(it.next(), Some(OsStr::new("tmp")));
    assert_eq!(it.next(), Some(OsStr::new("foo.txt")));
    assert_eq!(it.next(), None)

Run

#### `pub fn display(&self) -> Display`[src]

        }
    }

Run
