Chat server which fails to compile:
use std::io::{TcpListener, TcpStream};
use std::io::{Acceptor, Listener};
enum StreamOrSlice {
Strm(TcpStream),
Slc(uint, [u8, ..1024])
}
fn main() {
let listener = TcpListener::bind("127.0.0.1", 5555);
// bind the listener to the specified address
let mut acceptor = listener.listen();
let (tx, rx) = channel();
spawn(proc() {
let mut streams: Vec<TcpStream> = Vec::new();
loop {
let rxd: StreamOrSlice = rx.recv();
match rxd {
Strm(stream) => {
streams.push(stream);
}
Slc(len, buf) => {
for stream in streams.iter_mut() {
let _ = stream.write(buf.slice(0, len));
}
}
}
}
});
// accept connections and process them, spawning a new tasks for each one
for stream in acceptor.incoming() {
match stream {
Err(e) => { /* connection failed */ }
Ok(mut stream) => {
// connection succeeded
tx.send(Strm(stream.clone()));
let tx2 = tx.clone();
spawn(proc() {
let mut buf: [u8, ..1024] = [0, ..1024];
loop {
let len = stream.read(buf);
tx2.send(Slc(len.unwrap(), buf));
}
})
}
}
}
}
The error is:
Compiling chat v0.1.0 (file:///home/chris/rust/chat)
task 'rustc' has overflowed its stack
Could not compile `chat`.
Is this fixable in code, or is it a compiler bug?
Note: @Levans thanks for your help this evening.
