Trait Implementations

impl Buf for InputBuffer

pub fn remaining(&self) -> usize

Returns the number of bytes between the current position and the end of the buffer.

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

Returns a slice starting at the current position and of length between 0 and Buf::remaining(). Note that this can return shorter slice (this allows non-continuous internal representation).

pub fn advance(&mut self, size: usize)

Advance the internal cursor of the Buf

pub fn chunks_vectored(&'a self, dst: &mut [IoSlice<'a>]) -> usize

Fills dst with potentially multiple slices starting at self's current position.

pub fn has_remaining(&self) -> bool

Returns true if there are any more bytes to consume

pub fn copy_to_slice(&mut self, dst: &mut [u8])

Copies bytes from self into dst.
