Struct rustc_serialize::opaque::BufGuard

struct BufGuard<'a> {
    buffer: &'a mut [u8],
    encoder_buffered: &'a mut usize,
    encoder_flushed: &'a mut usize,
    flushed: usize,
}

Helper struct to ensure the buffer is updated after all the writes are complete. It tracks the number of written bytes and drains them all from the front of the buffer when dropped.

Fields

buffer: &'a mut [u8]

encoder_buffered: &'a mut usize

encoder_flushed: &'a mut usize

flushed: usize

Implementations

impl<'a> BufGuard<'a>

fn new(
    buffer: &'a mut [u8],
    encoder_buffered: &'a mut usize,
    encoder_flushed: &'a mut usize
) -> Self

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

The unwritten part of the buffer

fn consume(&mut self, amt: usize)

Flag some bytes as removed from the front of the buffer

fn done(&self) -> bool

true if all of the bytes have been written

Trait Implementations

impl Drop for BufGuard<'_>

fn drop(&mut self)

Executes the destructor for this type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
