Trait futures::prelude::AsyncReadExt[−][src]

pub trait AsyncReadExt: AsyncRead {
    fn copy_into<W>(&'a mut self, writer: &'a mut W) -> CopyInto<'a, Self, W>

}

An extension trait which adds utility methods to AsyncRead types.

Provided Methods

Creates a future which copies all the bytes from one object to another.

The returned future will copy all the bytes read from this AsyncRead into the writer specified. This future will only complete once the reader has hit EOF and all bytes have been written to and flushed from the writer provided.

On success the number of bytes is returned.

Tries to read some bytes directly into the given buf in asynchronous manner, returning a future type.

The returned future will resolve to the number of bytes read once the read operation is completed.

Creates a future which will read exactly enough bytes to fill buf, returning an error if EOF is hit sooner.

The returned future will resolve once the read operation is completed.

In the case of an error the buffer and the object will be discarded, with the error yielded.

Creates a future which will read all the bytes from this AsyncRead.

Helper method for splitting this read/write object into two halves.

The two halves returned implement the Read and Write traits, respectively.
