Examples

server.rs:

use enet_rs::enet::{
    ENET_HOST_ANY,
    ENetAddress,
    enet_host_create,
};

fn main() {
    let address = ENetAddress {
        host: ENET_HOST_ANY,
        port: 2555
    };

    unsafe {
        let server = enet_host_create(&address,
            max_peers,
            2,
            0,
            0);
        if server.is_null() {
            println!("An error occurred while trying to create an ENet server host.");
        }
    }
    
    loop {
        /* does nothing */
    }
}

client.rs:

use std::ptr::null;
use std::mem::MaybeUninit;
use std::ffi::CString;
use enet_rs::enet::{
    ENetEventType,
    enet_host_create,
    enet_address_set_host,
    enet_host_connect,
    enet_host_service,
    enet_peer_reset
};

fn main() {
    unsafe {
        let client = enet_host_create(null(),
            1,
            2,
            0,
            0);
        if client.is_null() {
            panic!("An error occurred while trying to create an ENet client host.")
        }

        let mut address_ = MaybeUninit::uninit();
        enet_address_set_host(address_.as_mut_ptr(), (&CString::new("127.0.0.1").unwrap()).as_ptr());
        let mut address = address_.assume_init();
        address.port = 2555;

        let peer = enet_host_connect(client, &address, 2, 0);
        if peer.is_null() {
            println!("No available peers for initiating an ENet connection.\n");
        }

        let mut event_ = MaybeUninit::uninit();
        loop {
            if enet_host_service(client, event_.as_mut_ptr(), 5000) > 0 {
                let event = event_.assume_init();
                match event.type_ {
                    ENetEventType::ENET_EVENT_TYPE_CONNECT => {
                        println!("connected to server.")
                    }
                    _ => enet_peer_reset(peer)
                }
            }
        }
    }
}
