Trait rsfs::Permissions [−] [src]

pub trait Permissions: Clone + PartialEq + Eq + Debug {
    fn readonly(&self) -> bool;
    fn set_readonly(&mut self, readonly: bool);
}

Representation of the various permissions on a file.

This trait only requires readonly and set_readonly, which are the only two "cross platform" functions provided in std::fs. However, the unix_ext module has a useful PermissionsExt trait to complement this one.

Required Methods

Returns whether these permissions have readonly set.

Examples

use rsfs::*;
use rsfs::mem::FS;
let fs = FS::new();

let file = fs.create_file("foo.txt")?;
let metadata = file.metadata()?;

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

Modifies the readonly fly for these permissions.

This does not modify the filesystem. To modify the filesystem, use the filesystem's set_permissions function.

Examples

use rsfs::*;
use rsfs::mem::FS;
let fs = FS::new();

let file = fs.create_file("foo.txt")?;
let metadata = file.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());
