A simple http server library.

Basic get request

use chuchi::{get, Res};

struct GlobalName(String);

// handle a simple get request
#[get("/")]
fn root(global_name: Res<GlobalName>) -> String {
	format!("Hi, this is {}", global_name.0)
}

#[tokio::main]
async fn main() {
	let mut server = chuchi::build("0.0.0.0:3000").await
		.expect("Failed to parse address");

	server.add_resource(GlobalName("fire".into()));
	server.add_route(root);

	server.run().await.unwrap();
}

For more examples look in the examples directory and the test directory.
