Struct yukikaze::utils::BytesWriter

pub struct BytesWriter { /* fields omitted */ }

Convenience wrapper over bytes::BytesMut

Provides io::Write that automatically resizes.

Methods

impl BytesWriter

pub fn new() -> Self

Creates new instance with default capacity 4096

pub fn with_smol_capacity() -> Self

Creates new instance with smol capacity 64

pub fn with_capacity(capacity: usize) -> Self

Creates new instance with provided capacity

pub fn into_inner(self) -> BytesMut

Converts into underlying bytes::BytesMut

pub fn freeze(&mut self) -> Bytes

Converts into bytes::Bytes

pub fn len(&self) -> usize

Returns buffer length.

pub fn split_off(&mut self, at: usize) -> Self

Splits off, the same as bytes::BytesMut::split_off

pub fn reserve(&mut self, add: usize)

Reserve extra memory, the same as bytes::BytesMut::reserve

Trait Implementations

impl Write for BytesWriter

fn write(&mut self, buf: &[u8]) -> Result<usize>

Write a buffer into this writer, returning how many bytes were written.

fn write_all(&mut self, buf: &[u8]) -> Result<()>

Attempts to write an entire buffer into this writer.

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn write_fmt(&mut self, fmt: Arguments) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

Creates a "by reference" adaptor for this instance of Write.
