Struct async_std::io::StdinLock

pub struct StdinLock<'a>(_);

This is supported on unstable only.

A locked reference to the Stdin handle.

This handle implements the Read traits, and is constructed via the Stdin::lock method.

Trait Implementations

impl<'_> Read for StdinLock<'_>

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>>

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

fn read<'a>(&'a mut self, buf: &'a mut [u8]) -> ImplFuture<Result<usize>> where
    Self: Unpin, 

Reads some bytes from the byte stream.

fn read_vectored<'a>(
    &'a mut self,
    bufs: &'a mut [IoSliceMut<'a>]
) -> ImplFuture<Result<usize>> where
    Self: Unpin, 

Like [read], except that it reads into a slice of buffers.

fn read_to_end<'a>(
    &'a mut self,
    buf: &'a mut Vec<u8>
) -> ImplFuture<Result<usize>> where
    Self: Unpin, 

Reads all bytes from the byte stream.

fn read_to_string<'a>(
    &'a mut self,
    buf: &'a mut String
) -> ImplFuture<Result<usize>> where
    Self: Unpin, 

Reads all bytes from the byte stream and appends them into a string.

fn read_exact<'a>(&'a mut self, buf: &'a mut [u8]) -> ImplFuture<Result<()>> where
    Self: Unpin, 

Reads the exact number of bytes required to fill buf.

fn take(self, limit: u64) -> Take<Self> where
    Self: Sized, 

Creates an adaptor which will read at most limit bytes from it.

fn by_ref(&mut self) -> &mut Self where
    Self: Sized, 

Creates a "by reference" adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self> where
    Self: Sized, 

Transforms this Read instance to a Stream over its bytes.

fn chain<R: Read>(self, next: R) -> Chain<Self, R> where
    Self: Sized, 

Creates an adaptor which will chain this stream with another.

impl<'_> Send for StdinLock<'_>

impl<'a> Debug for StdinLock<'a>

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

Formats the value using the given formatter.
