Struct async_prost::AsyncProstReader

pub struct AsyncProstReader<R, T, D> { /* fields omitted */ }

A wrapper around an async reader that produces an asynchronous stream of prost-decoded values

Implementations

impl<R, T, D> AsyncProstReader<R, T, D>

pub fn new(reader: R) -> Self

create a new reader

pub fn get_ref(&self) -> &R

gets a reference to the underlying reader

pub fn get_mut(&mut self) -> &mut R

gets a mutable reference to the underlying reader

pub fn buffer(&self) -> &[u8]

returns a reference to the internally buffered data

pub fn into_inner(self) -> R

unwrap the AsyncProstReader, returning the underlying reader

Trait Implementations

impl<R: Debug, T: Debug, D: Debug> Debug for AsyncProstReader<R, T, D>

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

Formats the value using the given formatter.

impl<R, T, D> Default for AsyncProstReader<R, T, D> where
    R: Default, 

fn default() -> Self

Returns the “default value” for a type.

impl<R, T, D> From<R> for AsyncProstReader<R, T, D>

fn from(reader: R) -> Self

Performs the conversion.

impl<R, T> Stream for AsyncProstReader<R, T, AsyncDestination> where
    T: Message + Default,
    R: AsyncRead + Unpin, 

type Item = Result<T, Error>

Values yielded by the stream.

fn poll_next(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>
) -> Poll<Option<Self::Item>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

pub fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.

impl<R, T> Stream for AsyncProstReader<R, T, AsyncFrameDestination> where
    R: AsyncRead + Unpin,
    T: Framed + Default, 

type Item = Result<T, Error>

Values yielded by the stream.

fn poll_next(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>
) -> Poll<Option<Self::Item>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

pub fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.

impl<R, T, D> Unpin for AsyncProstReader<R, T, D> where
    R: Unpin,
