# Function std::fs::set_permissions [−] [src]

    pub fn set_permissions<P: AsRef<Path>>(path: P, perm: Permissions) -> Result<()>

Changes the permissions found on a file or a directory.

# Platform-specific behavior

This function currently corresponds to the `chmod` function on Unix and the `SetFileAttributes` function on Windows. Note that, this may change in the future.

# Errors

This function will return an error in the following situations, but is not limited to just these cases:

- `path` does not exist.
- The user lacks the permission to change attributes of the file.

# Examples

fn main() { fn foo() -> std::io::Result<()> { use std::fs; let mut perms = try!(fs::metadata("foo.txt")).permissions(); perms.set_readonly(true); try!(fs::set_permissions("foo.txt", perms)); Ok(()) } }

    use std::fs;

    let mut perms = try!(fs::metadata("foo.txt")).permissions();
    perms.set_readonly(true);
    try!(fs::set_permissions("foo.txt", perms));

## 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`)
