Trait std::os::unix::fs::PermissionsExt

pub trait PermissionsExt {
    fn mode(&self) -> u32;
    fn set_mode(&mut self, mode: u32);
    fn from_mode(mode: u32) -> Self;
}
This is supported on Unix only.

Unix-specific extensions to fs::Permissions.

Required methods

fn mode(&self) -> u32

This is supported on Unix only.

Returns the underlying raw st_mode bits that contain the standard Unix permissions for this file.

Examples

use std::fs::File;
use std::os::unix::fs::PermissionsExt;

fn main() -> std::io::Result<()> {
    let f = File::create("foo.txt")?;
    let metadata = f.metadata()?;
    let permissions = metadata.permissions();

    println!("permissions: {:o}", permissions.mode());
    Ok(()) }

fn set_mode(&mut self, mode: u32)

This is supported on Unix only.

Sets the underlying raw bits for this set of permissions.

Examples

use std::fs::File;
use std::os::unix::fs::PermissionsExt;

fn main() -> std::io::Result<()> {
    let f = File::create("foo.txt")?;
    let metadata = f.metadata()?;
    let mut permissions = metadata.permissions();

    permissions.set_mode(0o644); // Read/write for owner and read for others.
    assert_eq!(permissions.mode(), 0o644);
    Ok(()) }

fn from_mode(mode: u32) -> Self

This is supported on Unix only.

Creates a new instance of Permissions from the given set of Unix permission bits.

Examples

use std::fs::Permissions;
use std::os::unix::fs::PermissionsExt;

// Read/write for owner and read for others.
let permissions = Permissions::from_mode(0o644);
assert_eq!(permissions.mode(), 0o644);
