kcp-rust-native Build Status ChatOnDiscord Crate

KCP bindings for Rust.

Get started

# Cargo.toml
[dependencies]
kcp-rust-native = "0.1.0"

Example

use kcp_rust_native::*;

unsafe extern "C" fn udp_output (
    buf: *const ::std::os::raw::c_char,
    len: ::std::os::raw::c_int,
    kcp: *mut IKCPCB,
    _user: *mut ::std::os::raw::c_void,
) -> ::std::os::raw::c_int {
    ikcp_input(kcp, buf, len as i64);
    return 0;
}

fn main() {

    let kcp = unsafe { ikcp_create(0x11223344, std::ptr::null_mut()) }; 

    unsafe { (*kcp).output = Some(udp_output) };

    let mut buf : [u8 ; 20] = [0; 20];
    let mut ori_data = String::from("hello world");
    let mut tick : u32 = 0;
    unsafe { 
        loop {
            let data = ori_data.as_bytes_mut().as_mut_ptr();
            ikcp_update(kcp, tick);
            tick += 100;

            ikcp_send(kcp, data as *const i8 , 11);
            ikcp_update(kcp, tick);

            let received = ikcp_recv(kcp, buf.as_mut_ptr() as *mut i8, 20);
            if received != -1 {
                println!("{}" , String::from_utf8(buf[..{received as usize}].to_vec()).unwrap());
            }
        }
        ikcp_release(kcp);
    };
}
