Struct StdinLock

pub struct StdinLock<'a>(/* private fields */);

A locked reference to the Stdin handle.

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

Trait Implementations

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

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

Formats the value using the given formatter.

impl Read for StdinLock<'_>

Available on unstable only.

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<'_>
