Rust Stackfull Coroutine Library.
May is a high performance stackfull coroutine library that can be thought of rust version goroutine. you can use it easily to design and develop massive concurrent programs in rust.
```rust /// a naive echo server extern crate may;
use may::coroutine; use may::net::TcpListener; use std::io::{Read, Write};
fn main() { let listener = TcpListener::bind("127.0.0.1:8000").unwrap(); while let Ok((mut stream, )) = listener.accept() { coroutine::spawn(move || { let mut buf = vec![0; 1024 * 16]; // alloc in heap! while let Ok(n) = stream.read(&mut buf) { if n == 0 { break; } stream.writeall(&buf[0..n]).unwrap(); } }); } }
```
just a simple comparation with the rust echo server implemented in tokio to get a sense about May
Machine Specs:
Echo server client:
sh
$ cargo build --example=echo_client --release
tokio echo server
run the server by default with 2 threads in another terminal
sh
$ cd tokio-core
$ cargo run --example=echo-threads --release
```sh $ target/release/examples/echo_client -t 2 -c 100 -l 100 -a 127.0.0.1:8080 ==================Benchmarking: 127.0.0.1:8080================== 100 clients, running 100 bytes, 10 sec.
