Simple Stream: Build Fast and Simple WebSockets in Rust


simple-stream is a buffered stream wrapper over anything that implements std::io::Read and std::io::Write. It works by buffering all reads and checking the buffers against a FrameBuilder, which will inform the stream that a complete Frame has been received, and removes it out of the buffer.

The crate comes with a few types of Framing options, and provides both a plain text and encrypted stream via rust-openssl.


Example Usage

extern crate simple_stream as ss;

use std::net::TcpStream;

use ss::frame::{SimpleFrame, SimpleFrameBuilder};
use ss::{Plain, NonBlocking};

fn main() {
    // Create some non-blocking type that implements Read + Write
    let stream = TcpStream::connect("").unwrap();

    // Create a Plain Text stream that sends and receives messages in the
    // `SimpleFrame` format.
    let mut plain_stream = Plain::<TcpStream, SimpleFrameBuilder>::new(stream);

    // Perform a non-blocking write
    let buf = vec!(1, 2, 3, 4);
    let frame = SimpleFrame::new(&buf[..]);
    match plain_stream.nb_send(&frame) {
        Ok(_) => { }
        Err(e) => println!("Error during write: {}", e)

    // Perform a non-blocking read
    match plain_stream.nb_recv() {
        Ok(frames) => {
            for _ in frames {
                // Do stuff with received frames
        Err(e) => println!("Error during read: {}", e)
