websocket-lite
A fast, low-overhead WebSocket client.
This library is optimised for receiving a high volume of messages over a long period. A key feature is that is makes no memory allocations once the connection is set up and the initial messages have been sent and received; it reuses a single pair of buffers, which are sized for the longest message seen so far.
Only asynchronous access is provided at present. native_tls provides the TLS functionality for wss://... servers.
This crate is fully conformant with the Autobahn test suite fuzzingserver module.
