Struct libp2p_core::muxing::SubstreamBox

pub struct SubstreamBox(/* private fields */);

Abstract type for asynchronous reading and writing.

A SubstreamBox erases the concrete type it is given and only retains its AsyncRead and AsyncWrite capabilities.

Implementations

impl SubstreamBox

pub fn new<S: AsyncRead + AsyncWrite + Send + 'static>(stream: S) -> Self

Construct a new SubstreamBox from something that implements [AsyncRead] and [AsyncWrite].

Trait Implementations

impl AsyncRead for SubstreamBox

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.

impl AsyncWrite for SubstreamBox

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

Attempt to write bytes from buf into the object.

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

Attempt to write bytes from bufs into the object using vectored IO operations.

fn poll_flush(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Result<()>>

Attempt to flush the object, ensuring that any buffered data reach their destination.

fn poll_close(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Result<()>>

Attempt to close the object.

impl Debug for SubstreamBox

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

Formats the value using the given formatter.
