tokio-try-read-full

This crate complemnts tokio-io's read_exact for scenarios where you want to read as many bytes as possible into a buffer until either the buffer is full or the reader returns EOF.

lib.rs:

This library provides a future to complement tokio-io's read_exact. Sometimes, you want to read as much as possible into a large buffer. It does not have to be an error to not fill the buffer.
