Trait RawOsStrCow

pub trait RawOsStrCow<'a>: Sealed {
    // Required methods
    fn from_os_str(string: Cow<'a, OsStr>) -> Self;
    fn into_os_str(self) -> Cow<'a, OsStr>;
    fn into_raw_bytes(self) -> Cow<'a, [u8]>;
}

Extensions to Cow<RawOsStr> for additional conversions.

Required Methods

fn from_os_str(string: Cow<'a, OsStr>) -> Self

Converts a platform-native string back to this representation.

Nightly Notes

This method does not require copying or encoding conversion.

Examples

use std::borrow::Cow;
use std::env;

use os_str_bytes::RawOsStr;
use os_str_bytes::RawOsStrCow;

let os_string = Cow::Owned(env::current_exe()?.into_os_string());
println!("{:?}", Cow::from_os_str(os_string));

fn into_os_str(self) -> Cow<'a, OsStr>

Converts this representation back to a platform-native string.

Nightly Notes

This method does not require copying or encoding conversion.

Examples

use std::env;

use os_str_bytes::RawOsStr;
use os_str_bytes::RawOsStrCow;

let os_string = env::current_exe()?.into_os_string();
let raw = RawOsStr::new(&os_string);
assert_eq!(os_string, raw.into_os_str());

fn into_raw_bytes(self) -> Cow<'a, [u8]>

👎Deprecated: enable the ‘conversions’ feature

Returns the byte string stored by this container.

The returned string will use an unspecified encoding.

Examples

use std::borrow::Cow;

use os_str_bytes::RawOsStr;
use os_str_bytes::RawOsStrCow;

let string = "foobar";
let raw = Cow::Borrowed(RawOsStr::from_str(string));
assert_eq!(string.as_bytes(), &*raw.into_raw_bytes());

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
