Trait std::os::unix::ffi::OsStrExt

pub trait OsStrExt {
    fn from_bytes(slice: &[u8]) -> &Self;
    fn as_bytes(&self) -> &[u8];
}

This is supported on Unix only.

Unix-specific extensions to OsStr.

Required Methods

Important traits for &'a mut I

impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;impl<'a, R: Read + ?Sized> Read for &'a mut Rimpl<'a, W: Write + ?Sized> Write for &'a mut W

fn from_bytes(slice: &[u8]) -> &Self

This is supported on Unix only.

Creates an OsStr from a byte slice.

Examples

use std::ffi::OsStr;
use std::os::unix::ffi::OsStrExt;

let bytes = b"foo";
let os_str = OsStr::from_bytes(bytes);
assert_eq!(os_str.to_str(), Some("foo"));

Important traits for &'a [u8]

impl<'a> Read for &'a [u8]impl<'a> Write for &'a mut [u8]

fn as_bytes(&self) -> &[u8]

This is supported on Unix only.

Gets the underlying byte view of the OsStr slice.

Examples

use std::ffi::OsStr;
use std::os::unix::ffi::OsStrExt;

let mut os_str = OsStr::new("foo");
let bytes = os_str.as_bytes();
assert_eq!(bytes, b"foo");
