Struct ReadOnly 

pub struct ReadOnly<R>(pub R);

Available on crate feature io only.

An adaptor which implements Splittable for any AsyncRead, with the write half being ().

This can be used to create a framed stream with only a reader, using the AsyncReadExt::framed or AsyncReadExt::bytes method.

Trait Implementations

impl<R> AsyncRead for ReadOnly<R>

where R: AsyncRead,

async fn read<T>(&mut self, buf: T) -> BufResult<usize, T>

where T: IoBufMut,

Read some bytes from this source into the IoBufMut buffer and return a BufResult, consisting of the buffer and a usize indicating how many bytes were read.

async fn read_vectored<T>(&mut self, buf: T) -> BufResult<usize, T>

where T: IoVectoredBufMut,

Like read, except that it reads into a type implements IoVectoredBufMut.

impl<R> Splittable for ReadOnly<R>

type ReadHalf = R

The type of the read half, which normally implements AsyncRead or AsyncReadAt.

type WriteHalf = ()

The type of the write half, which normally implements AsyncWrite or AsyncWriteAt.

fn split( self, ) -> (<ReadOnly<R> as Splittable>::ReadHalf, <ReadOnly<R> as Splittable>::WriteHalf)

Consumes self and returns a tuple containing separate read and write halves.
