# Enum std::path::Component 1.0.0 [−] [src]

    pub enum Component<'a> {
        Prefix(PrefixComponent<'a>),
        RootDir,
        CurDir,
        ParentDir,
        Normal(&'a OsStr),
    }

A single component of a path.

A `Component` roughly corresponds to a substring between path separators (`/` or `\`).

This `enum` is created by iterating over `Components`, which in turn is created by the `components` method on `Path`.

# Examples

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

    let path = Path::new("/tmp/foo/bar.txt");
    let components = path.components().collect::<Vec<_>>();
    assert_eq!(&components, &[
        Component::RootDir,
        Component::Normal("tmp".as_ref()),
        Component::Normal("foo".as_ref()),
        Component::Normal("bar.txt".as_ref()),
    ]);Run

## Variants

`Prefix(PrefixComponent<'a>)`

A Windows path prefix, e.g. `C:` or `\\server\share`.

There is a large variety of prefix types, see `Prefix`'s documentation for more.

Does not occur on Unix.

`RootDir`

The root directory component, appears after any prefix and before anything else.

It represents a separator that designates that a path starts from root.

`CurDir`

A reference to the current directory, i.e. `.`.

`ParentDir`

A reference to the parent directory, i.e. `..`.

`Normal(&'a OsStr)`

A normal component, e.g. `a` and `b` in `a/b`.

This variant is the most common one, it represents references to files or directories.

## Methods

### `impl<'a> Component<'a>`
[src]

#### `pub fn as_os_str(self) -> &'a OsStr`

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
