Rust Component Layer for D3 -- A Framework for Server Development

The components layer provides an organization hierarchy for machines. It is based upon a Component/Coordinator/Connector model, and while not the only possible model, it is one I like. This layer is where the network is exposed. It is an adapter wrapping Mio.

Usage

Add this to your Cargo.toml:

[dependencies]
d3-derive = "0.1.0"
d3-core = "0.1.0"
d3-components = "0.1.0"

Example Listening on an address:port

#[macro_use]
extern crate d3_derive;

use d3_core::machine_impl::*;
use d3_core::executor;
use d3_components::network;

// A trivial Alice
pub struct Alice {}

// Implement the Machine trait for Alice
impl Machine<network::NetCmd> for Alice {
     fn receive(&self, cmd: StateTable) {
     }
}

// Start the scheduler and executor and network
executor::start_server();
network::start_network();

// create the Machine from Alice, getting back a machine and Sender<StateTable>.
let (alice, sender) = executor::connect(Alice{});

// send a command to the network asking for Alice to 
// be notified if a connection is received for 127.0.0.1:4000
let cmd = NetCmd::BindListener("127.0.0.1:4000".to_string, sender);
network::get_network_sender().send(cmd).expect("send failed");

// Stop the scheduler and executor and network
network::start_network();
executor::stop_server();
