Trait Implementations

impl<'a, R: Debug + ?Sized> Debug for FillBuf<'a, R>

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

Formats the value using the given formatter.

impl<'a, R: AsyncBufRead + ?Sized + Unpin> Future for FillBuf<'a, R>

type Output = Result<&'a [u8], Error>

The type of value produced on completion.

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

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
