`zap` :zap:

The mission of zap is, to deliver a fast rust web framework that just supports the basics.

About

This code is based on tokio's minihttp project, so a big thanks to them. (source)

How to use

Add the following to your Cargo.toml:

[dependencies]
zap = { git = "https://github.com/oldaniel/zap" }

Speed

So zap is not only fast, it is wapping x2,7 times faster than iron which is based on hyper. Benchmarks below:

Benchmark Code

Iron

This code had been taken from the ironframework.io webpage.

extern crate iron;

use iron::prelude::*;
use iron::status;

fn main() {
    fn hello_world(_: &mut Request) -> IronResult<Response> {
        Ok(Response::with((status::Ok, "Hello World!")))
    }

    let _server = Iron::new(hello_world).http("localhost:3000").unwrap();
    println!("On 3000");
}

Zap

This example can be run, by:

$ git clone https://github.com/oldaniel/zap && cd zap
$ cargo run --example hello-world --release

extern crate zap;

use std::io;

use zap::{Server, Http, Handler, ZapResult, Request, Response};

struct HelloWorld;

impl Handler for HelloWorld {
    type Request = Request;
    type Response = Response;
    type Error = io::Error;
    type Future = ZapResult;

    fn call(&self, _: Request) -> ZapResult {
        let mut resp = Response::new();

        resp.body("Hello World!");

        resp.ok()
    }
}

fn main() {
    let addr = "0.0.0.0:8080".parse().unwrap();
    let mut server = Server::new(Http, addr);
    server.threads(8);
    server.serve(|| Ok(HelloWorld));
}

Benchmark Results

The benchmarks had been done with the following command: wrk -t16 -c500 -d10s http://127.0.0.1:8080 --latency

Technical details about the server:

Intel Core I7-6700K, hyperthreaded
16GB RAM, 2400MHZ

Todo

Some things we still need to make:

Make it faster
URL and body parsing
Request key storing
