Trait Implementations

impl AsyncBufRead for Empty

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

Attempts 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 ReadBuf<'_>
) -> Poll<Result<()>>

Attempts to read from the AsyncRead into buf.

impl Debug for Empty

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

Formats the value using the given formatter.
