Struct tokio::io::util::read::Read

pub struct Read<'a, R: ?Sized> {
    reader: &'a mut R,
    buf: &'a mut [u8],
    _pin: PhantomPinned,
}

A future which can be used to easily read available number of bytes to fill a buffer.

Created by the read function.

Fields

reader: &'a mut R

buf: &'a mut [u8]

_pin: PhantomPinned

Trait Implementations

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

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

Formats the value using the given formatter.

impl<R> Future for Read<'_, R>

where R: AsyncRead + Unpin + ?Sized,

type Output = Result<usize, Error>

The type of value produced on completion.

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

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

impl<'__pin, 'a, R: ?Sized> Unpin for Read<'a, R>

where PinnedFieldsOf<__Origin<'__pin, 'a, R>>: Unpin,
