[−][src]Struct bytes::buf::Writer
A BufMut
adapter which implements io::Write
for the inner value.
This struct is generally created by calling writer()
on BufMut
. See
documentation of writer()
for more
details.
Methods
impl<B: BufMut> Writer<B>
[src]
pub fn get_ref(&self) -> &B
[src]
Gets a reference to the underlying BufMut
.
It is inadvisable to directly write to the underlying BufMut
.
Examples
use bytes::BufMut; let mut buf = Vec::with_capacity(1024).writer(); assert_eq!(1024, buf.get_ref().capacity());
pub fn get_mut(&mut self) -> &mut B
[src]
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());
pub fn into_inner(self) -> B
[src]
Consumes this Writer
, returning the underlying value.
Examples
use bytes::BufMut; use std::io::{self, Cursor}; let mut buf = vec![].writer(); let mut src = Cursor::new(b"hello world"); io::copy(&mut src, &mut buf).unwrap(); let buf = buf.into_inner(); assert_eq!(*buf, b"hello world"[..]);
