pub struct Empty { /* private fields */ }

Reader for the empty() function.

Trait Implementations

impl AsyncBufRead for Empty

fn poll_fill_buf<'a>( self: Pin<&'a mut Self>, _: &mut Context<'_>, ) -> Poll<Result<&'a [u8]>>

Attempt to return the contents of the internal buffer, filling it with more data from the inner reader if it is empty.

fn consume(self: Pin<&mut Self>, _: usize)

Tells this buffer that amt bytes have been consumed from the buffer, so they should no longer be returned in calls to poll_read.

impl AsyncRead for Empty

fn poll_read( self: Pin<&mut Self>, _: &mut Context<'_>, _: &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, Error>>

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

impl Debug for Empty

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

Formats the value using the given formatter.
