tokio-async-write-utility

Some helper functions for types impl AsyncWrite.

It currently provides the following functions through trait AsyncWriteUtility:

• fn poll_write_vectored_all(Pin<&mut Self>, &mut Context<'_>, &mut [IoSlice<'_>]) -> io::Result<()>

• fn write_vectored_all(&mut self, &mut [IoSlice<'_>]) -> WriteVectorizedAll

  which is equivalent to:

  async fn write_vectored_all(&mut self, &mut [IoSlice<'_>],) -> io::Result<()>
