Note about these docs

These docs are mostly copied verbatim from the UDT documentation. If you see references to the C++ function names instead of the rust function names, that's why.

UDT

Bindings to the UDT4 high performance data data transfer library

UDT follows closely the BSD socket API, but several of the functions have different semantics.

UDT is a high performance data transfer protocol - UDP-based data transfer protocol. It was designed for data intensive applications over high speed wide area networks, to overcome the efficiency and fairness problems of TCP. As its name indicates, UDT is built on top of UDP and it provides both reliable data streaming and messaging services.

Examples

To create a Datagram server, that can send and receive messages:

    use std::str::FromStr;
    use std::net::{SocketAddr, SocketAddrV4};
    use udt::*;

    let localhost = std::net::Ipv4Addr::from_str("127.0.0.1").unwrap();

    let sock = UdtSocket::new(SocketFamily::AFInet, SocketType::Stream).unwrap();
    sock.bind(SocketAddr::V4(SocketAddrV4::new(localhost, 0))).unwrap();
    let my_addr = sock.getsockname().unwrap();
    println!("Server bound to {:?}", my_addr);
    sock.listen(5).unwrap();
    let (mut new_socket, peer) = sock.accept().unwrap();
    println!("Received new connection from peer {:?}", peer);
