Trait OsStrExt

trait OsStrExt: Sealed

Windows-specific extensions to OsStr.

This trait is sealed: it cannot be implemented outside the standard library. This is so that future additional methods are not breaking changes.

Required Methods

fn encode_wide(self: &Self) -> EncodeWide<'_>

Re-encodes an OsStr as a wide character sequence, i.e., potentially ill-formed UTF-16.

This is lossless: calling OsStringExt::from_wide and then encode_wide on the result will yield the original code units. Note that the encoding does not add a final null terminator.

Examples

use std::ffi::OsString;
use std::os::windows::prelude::*;

// UTF-16 encoding for "Unicode".
let source = [0x0055, 0x006E, 0x0069, 0x0063, 0x006F, 0x0064, 0x0065];

let string = OsString::from_wide(&source[..]);

let result: Vec<u16> = string.encode_wide().collect();
assert_eq!(&source[..], &result[..]);
