Struct microasync_rt::io::read::ReadFuture

pub struct ReadFuture<'a, T>(_, _);

Trait Implementations

impl<'a> Future for ReadFuture<'a, File>

type Output = Result<usize, Error>

The type of value produced on completion.

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

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

impl<'a> Future for ReadFuture<'a, TcpStream>

type Output = Result<usize, Error>

The type of value produced on completion.

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

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

impl<'a> Future for ReadFuture<'a, UdpSocket>

type Output = Result<usize, Error>

The type of value produced on completion.

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

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

impl<'a, T> ReadAsync<'a, usize, ReadFuture<'a, T>, ReadExactFuture<'a, T>> for Twhere
    ReadFuture<'a, T>: Future<Output = Result<usize, Error>> + 'a,
    ReadExactFuture<'a, T>: Future<Output = Result<(), Error>> + 'a,

fn read(&'a mut self, bytes: &'a mut [u8]) -> ReadFuture<'a, T>

Async equivalent to std::io::Read::read.

fn read_exact(&'a mut self, bytes: &'a mut [u8]) -> ReadExactFuture<'a, T>

Async equivalent to std::io::Read::read_exact. This MAY read more bytes than the length of the array if needed (namely, when using UdpSockets), but will avoid doing so to the best of its ability.
