Struct SliceReader

pub struct SliceReader<'a> { /* private fields */ }

An AsyncRead implementation capable of reading a [&[u8]].

Implementations

impl<'a> SliceReader<'a>

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

Create a new SliceReader for bytes.

Trait Implementations

impl<'a> AsyncRead for SliceReader<'a>

fn poll_read( self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &mut [u8], ) -> Poll<Result<usize>>

Attempt to read from the AsyncRead into buf.

fn poll_read_vectored( self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &mut [IoSliceMut<'_>], ) -> Poll<Result<usize, Error>>

Attempt to read from the AsyncRead into bufs using vectored IO operations.

impl<'a> AsyncSeekForward for SliceReader<'a>

fn poll_seek_forward( self: Pin<&mut Self>, _cx: &mut Context<'_>, offset: u64, ) -> Poll<Result<u64>>

Attempts to asynchronously seek forward by a specified number of bytes from the current cursor position.

impl Reader for SliceReader<'_>

fn read_to_end<'a>( &'a mut self, buf: &'a mut Vec<u8>, ) -> StackFuture<'a, Result<usize>, STACK_FUTURE_SIZE>

Reads the entire contents of this reader and appends them to a vec.
