Struct iovec::IoVec

pub struct IoVec { /* fields omitted */ }

A specialized byte slice type for performing vectored I/O operations.

On all systems, the types needed to perform vectored I/O systems have the same size as Rust's [slice]. However, the layout is not necessarily the same. IoVec provides a portable compatibility layer.

The IoVec behaves like like a Rust [slice], providing the same functions. It also provides conversion functions to and from the OS specific vectored types.

Examples

use iovec::IoVec;

let mut data = vec![];
data.extend_from_slice(b"hello");

let iovec: &IoVec = data.as_slice().into();

assert_eq!(&iovec[..], &b"hello"[..]);

Panics

Attempting to convert a zero-length slice or a slice longer than MAX_LENGTH to an IoVec will result in a panic.

Methods

impl IoVec

pub fn from_bytes(slice: &[u8]) -> Option<&IoVec>

pub fn from_bytes_mut(slice: &mut [u8]) -> Option<&mut IoVec>

Trait Implementations

impl Deref for IoVec

type Target = [u8]

The resulting type after dereferencing.

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

Dereferences the value.

impl DerefMut for IoVec

fn deref_mut(&mut self) -> &mut [u8]

Mutably dereferences the value.
