Trait AsyncWriteExt

pub trait AsyncWriteExt: AsyncWrite {
    // Provided methods
    fn flush(self) -> Flush<Self>
       where Self: Sized { ... }
    fn close(self) -> Close<Self>
       where Self: Sized { ... }
    fn write_all<T>(self, buf: T) -> WriteAll<Self, T>
       where T: AsRef<[u8]>,
             Self: Sized { ... }
}

An extension trait which adds utility methods to AsyncWrite types.

Provided Methods

fn flush(self) -> Flush<Self>

where Self: Sized,

Creates a future which will entirely flush this AsyncWrite and then return self.

This function will consume self if an error occurs.

fn close(self) -> Close<Self>

where Self: Sized,

Creates a future which will entirely close this AsyncWrite and then return self.

This function will consume the object provided if an error occurs.

fn write_all<T>(self, buf: T) -> WriteAll<Self, T>

where T: AsRef<[u8]>, Self: Sized,

Write a Buf into this value, returning how many bytes were written. Creates a future that will write the entire contents of the buffer buf into this AsyncWrite.

The returned future will not complete until all the data has been written. The future will resolve to a tuple of self and buf (so the buffer can be reused as needed).

Any error which happens during writing will cause both the stream and the buffer to be destroyed.

The buf parameter here only requires the AsRef<[u8]> trait, which should be broadly applicable to accepting data which can be converted to a slice. The Window struct is also available in this crate to provide a different window into a slice if necessary.
