impl<B: BufMut> Writer<B>

fn get_ref(&self) -> &B

Gets a reference to the underlying BufMut.

It is inadvisable to directly write to the underlying BufMut.

Examples

use bytes::BufMut;

let buf = Vec::with_capacity(1024).writer();

assert_eq!(1024, buf.get_ref().capacity());

fn get_mut(&mut self) -> &mut B

Gets a mutable reference to the underlying BufMut.

It is inadvisable to directly write to the underlying BufMut.

Examples

use bytes::BufMut;

let mut buf = vec![].writer();

buf.get_mut().reserve(1024);

assert_eq!(1024, buf.get_ref().capacity());

fn into_inner(self) -> B

Consumes this Writer, returning the underlying value.

Examples

use bytes::BufMut;
use std::io;

let mut buf = vec![].writer();
let mut src = &b"hello world"[..];

io::copy(&mut src, &mut buf).unwrap();

let buf = buf.into_inner();
assert_eq!(*buf, b"hello world"[..]);
