# Struct bitflags::__core::fs::Permissions [−] [src]

    pub struct Permissions(_);

1.0.0

Representation of the various permissions on a file.

This module only currently provides one bit of information, `readonly`, which is exposed on all currently supported platforms. Unix-specific functionality, such as mode bits, is available through the `os::unix::PermissionsExt` trait.

## Methods

### `impl Permissions`

#### `fn readonly(&self) -> bool`

Returns whether these permissions describe a readonly file.

# Examples

    use std::fs::File;

    let mut f = try!(File::create("foo.txt"));
    let metadata = try!(f.metadata());

    assert_eq!(false, metadata.permissions().readonly());

#### `fn set_readonly(&mut self, readonly: bool)`

Modifies the readonly flag for this set of permissions.

This operation does not modify the filesystem. To modify the filesystem use the `fs::set_permissions` function.

# Examples

    use std::fs::File;

    let f = try!(File::create("foo.txt"));
    let metadata = try!(f.metadata());
    let mut permissions = metadata.permissions();

    permissions.set_readonly(true);

    // filesystem doesn't change
    assert_eq!(false, metadata.permissions().readonly());

    // just this particular `permissions`.
    assert_eq!(true, permissions.readonly());

## 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`)
