Badge with github icon Badge with document icon

Amiya is a experimental middleware-based minimalism async HTTP server framework, built up on smol-rs related asynchronous components.

It's currently still working in progress and in a very early alpha stage.

API design may changes, DO NOT use it in any condition except for test or study!

Goal

The goal of this project is try to build a (by importance order):

  • Safe, with #![forbid(unsafe_code)]
  • Async
  • Middleware-based
  • Minimalism
  • Easy to use
  • Easy to extend

HTTP framework for myself to write simple web services.

Amiya uses async-h1 to parse and process requests, so only HTTP version 1.1 is supported for now. HTTP 1.0 or 2.0 is not in goal list, at least in the near future.

Performance is NOT in the list too, after all, Amiya is just a experimental for now, it uses many heap alloc (Box) and dynamic dispatch (Trait Object) so there may be some performance loss compare to use async-h1 directly.

Have a Taste

To start a very simple HTTP service that returns Hello World to the client in all paths:

use amiya::m;

fn main() {
    let app = amiya::new().uses(m!(ctx =>
        ctx.resp.set_body(format!("Hello World from: {}", ctx.path()));
    ));

    app.listen("[::]:8080").unwrap();

    // ... do other things you want ...
    // ... Amiya server will not block your thread ...
}

Amiya has a built-in multi-thread async executor powered by async-executor and async-io, http server will run in it. So Amiya::listen is just a normal non-async method, and do not block your thread.

Examples

To run examples, run

cargo run --example # show example list
cargo run --example hello # run hello

Top level document of crate has a brief description of concepts used in this framework, I recommend give it a read first, and then check those examples to get a more intuitive understanding:

Most of those example will use builtin executor, see example/tokio_executor.rs for how to use a custom executor with Amiya.
