Important traits for &'_ mut I

impl<'_, I> Iterator for &'_ mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;impl<'_, F> Future for &'_ mut F where

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 &'_ [u8]

impl<'_> Read for &'_ [u8]impl<'_> Write for &'_ 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");
