Struct BufferWriter 

pub struct BufferWriter<'a>(/* private fields */);

A zero-copy mutable buffer writer.

Implementations

impl<'a> BufferWriter<'a>

pub fn new(bytes: &'a mut [u8]) -> Self

Creates an BufferWriter by using bytes as inner buffer.

Inner offset is initialized to zero.

pub fn capacity(&self) -> usize

Returns the remaining capacity in the buffer.

pub fn offset(&self) -> usize

Returns the current offset of the buffer.

pub fn buffer_written(&self) -> &[u8]

Returns the portion of the inner buffer written so far.

Trait Implementations

impl BytesWriter for BufferWriter<'_>

fn put_varint(&mut self, varint: VarInt) -> Result<(), EndOfBuffer>

Writes an unsigned variable-length integer in network byte-order at the current offset and advances the offset.

fn put_bytes(&mut self, bytes: &[u8]) -> Result<(), EndOfBuffer>

Writes (by copy) all bytes at the current offset and advances it.
