Trait AsyncWriteBuffer 

pub trait AsyncWriteBuffer: DerefMut<Target = [u8]> + Unpin {
    type Error;
    type WriteAll<'a>: Future<Output = Result<(), Self::Error>>
       where Self: 'a;

    // Required methods
    fn poll_alloc(
        self: Pin<&mut Self>,
        cx: &mut Context<'_>,
    ) -> Poll<Result<(), Self::Error>>;
    fn write_all(&mut self, count: usize) -> Self::WriteAll<'_>;

    // Provided method
    fn alloc(&mut self) -> Alloc<'_, Self>  { ... }
}

Required Associated Types

type Error

type WriteAll<'a>: Future<Output = Result<(), Self::Error>> where Self: 'a

Required Methods

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

Allocate some fixed amount of bytes in the buffer.

fn write_all(&mut self, count: usize) -> Self::WriteAll<'_>

Send exactly count bytes from buffer. Remaining bytes are discarded.

Provided Methods

fn alloc(&mut self) -> Alloc<'_, Self>

Allocate some fixed amount of bytes in the buffer.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl<P: AsyncWrite + Unpin> AsyncWriteBuffer for IoBuffer<P>

type Error = Error

type WriteAll<'a> = WriteAll<'a, P> where P: 'a
