Trait Implementations

impl MutBuf for MutByteBuf

fn remaining(&self) -> usize

Returns the number of bytes that can be written to the MutBuf

unsafe fn advance(&mut self, cnt: usize)

Advance the internal cursor of the MutBuf

unsafe fn mut_bytes<'a>(&'a mut self) -> &'a mut [u8]

Returns a mutable slice starting at the current MutBuf position and of length between 0 and MutBuf::remaining().

fn has_remaining(&self) -> bool

Returns true iff there is any more space for bytes to be written

fn write_slice(&mut self, src: &[u8]) -> usize

Write bytes from the given slice into the MutBuf and advance the cursor by the number of bytes written. Returns the number of bytes written.

fn write_byte(&mut self, byte: u8) -> bool

Write a single byte to the MuBuf

impl Debug for MutByteBuf

fn fmt(&self, fmt: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Write for MutByteBuf

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

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

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_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.
