Struct std::fs::Permissions1.0.0 [] [src]

pub struct Permissions(_);

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.


impl Permissions

Returns whether these permissions describe a readonly file.


use std::fs::File;

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

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

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.


use std::fs::File;

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


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

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