import std.net

Every operation returns a Result, so network code reads like error handling with sockets.

Function	Signature	Description
net.tcp_connect	net.tcp_connect(addr: str, timeout_ms: int)	Connect (yields a stream)
net.tcp_listen	net.tcp_listen(addr: str)	Bind a listener
net.tcp_accept	net.tcp_accept(listener)	Accept one connection
net.tcp_write	net.tcp_write(stream, data: str)	Write bytes (count)
net.tcp_read	net.tcp_read(stream, max_bytes: int)	Read up to N bytes
net.tcp_readline	net.tcp_readline(stream)	Read one line
net.tcp_close	net.tcp_close(stream) -> bool	Close the stream
net.peer_addr	net.peer_addr(stream)	Remote address
net.local_addr	net.local_addr(stream)	Local address
net.set_read_timeout	net.set_read_timeout(stream, ms: int) -> bool	Read deadline
net.set_write_timeout	net.set_write_timeout(stream, ms: int) -> bool	Write deadline

import std.net

match net.tcp_connect("example.com:80", 5000) {
    .ok(stream) => {
        net.tcp_write(stream, "GET / HTTP/1.0\r\nHost: example.com\r\n\r\n")
        match net.tcp_read(stream, 4096) {
            .ok(body) => println(body),
            .err(e) => println("read failed: {e}"),
        }
        net.tcp_close(stream)
    },
    .err(e) => println("connect failed: {e}"),
}

For HTTP-shaped traffic prefer std.http — raw sockets are for protocols the standard library doesn’t speak yet.
