Struct neli::StreamWriteBuffer

pub struct StreamWriteBuffer<'a> { /* fields omitted */ }

A stream writer that will allow piece-by-piece writing of to a buffer

Methods

impl<'a> Write for StreamWriteBuffer<'a>

pub fn new_sized(buf: &'a mut [u8]) -> StreamWriteBuffer<'a>

Create a new slice-based stream writer that will error when written past buffer boundaries

pub fn set_size_hint(&mut self, size_hint: usize)

Set size hint

pub fn has_size_hint(&self) -> bool

Return true if a size hint is present

pub fn take_size_hint(&mut self) -> Option<usize>

Replace size hint with None and return Some(size_hint)

Set position of underlying cursor

Trait Implementations

impl<'a> AsRef<[u8]> for StreamWriteBuffer<'a>

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

Performs the conversion.

impl<'a> Write for StreamWriteBuffer<'a>

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

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

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

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_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

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.
