Struct merge_io::MergeIO

pub struct MergeIO<R, W> where
    R: AsyncRead + Unpin,
    W: AsyncWrite + Unpin,  { /* fields omitted */ }

Merged I/O, delegates reads and writes to the provided AsyncRead (R) and AsyncWrite (W).

Methods

impl<R, W> MergeIO<R, W> where
    R: AsyncRead + Unpin,
    W: AsyncWrite + Unpin, 

pub fn new(reader: R, writer: W) -> Self

Creates new MergeIO, that reads to reader and writes to writer.

pub fn reader(&self) -> &R

Provides access to reader.

pub fn writer(&self) -> &W

Provides access to writer.

pub fn reader_mut(&mut self) -> &mut R

Provides mut access to reader.

pub fn writer_mut(&mut self) -> &mut W

Provides mut access to writer.

pub fn into_inner(self) -> (R, W)

Deconstructs MergeIO into the reader and writer.
