grout

A dead simple hash-based HTTP router built on hyper.

use grout::{path, Body, Method, Request, Response, ResponseBuilder, RouterBuilder, Server};

async fn handler(params: Vec<String>, _req: Request) -> Response {
	Ok(ResponseBuilder::default().body(Body::empty())?)
}

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error + Send + Sync>> {
	let addr = ([127, 0, 0, 1], 3000).into();
	let router = RouterBuilder::default()
		.register(Method::GET, path![], handler)
		.register(Method::GET, path![foo / _], handler)
		.register(Method::POST, path![foo / _], handler)
		.build();

	let server = Server::bind(&addr).serve(router);
	println!("Listening on http://{}", addr);

	server.await?;
	Ok(())
}

Features

• HTTP method routing
• Route parameters (ordered, not keyed)
• Simple API

See the examples folder for example usage.

Limitations

• No state passing or any form of middleware
  • I recommend the state crate to inject outside structs into your route handlers
• No complex route matching
  • Perform complex validation in your route handlers
