# Trait std::os::unix::ffi::OsStrExt 1.0.0 [−] [src]

    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"));Run

ⓘImportant traits for &'a [u8]

### 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");Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
