Struct iovec::IoVec

pub struct IoVec<'a> { /* 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 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<'a> IoVec<'a>

pub fn from_bytes(slice: &'a [u8]) -> Self

Convert an IoVec from a byte slice

pub fn from_mut_slice<'b>(slice: &'b [IoVecMut<'a>]) -> &'b [Self]

Convert a slice of mutable iovecs to immutable iovecs

pub fn borrow(&self) -> IoVec

Immutable borrow of the iovec.
