A combinator library for building asynchronous HTTP services.

The concept and design was highly inspired by finch.

Features

• Asynchronous handling powerd by futures and Tokio
• Building an HTTP service by combining the primitive components
• Type-safe routing without (unstable) procedural macros

Example

#[macro_use]
extern crate finchers;

use finchers::prelude::*;

fn main() {
    let get_post = path!(@get / u64 /)
        .map(|id: u64| format!("GET: id={}", id));

    let create_post = path!(@post /)
        .and(endpoints::body::text())
        .map(|data: String| format!("POST: body={}", data));

    let post_api = path!(/ "posts")
        .and(get_post.or(create_post));

    finchers::launch(post_api)
        .start("127.0.0.1:4000");
}
