Implement actix::Handler for MyActor by having the handle method delegate to the associated method.Create a struct that represents the arguments of that method and derive actix::Message for it.Perhaps with the version 4 release of Actix itll be worth re-examining the performance gaps between these offerings. The benchmark has some outstanding complaints and Rocket has a new async-supporting version 0.5.0 which should be out of beta soon. Create the method that does something on the impl MyActor The benchmark ranked Actix version 3.3.2 the fastest against gotham, hyper, Rocket and warp.When adding messages to an actor, I noticed that it very often follows some specific pattern, that involves a bit of boilerplate code: Currently the SyncContext and SyncArbiter kind of live in their own world and are not well integrated in the whole ecosystem. Let addr = SyncArbiter::start( 10, || Redis::new( "redis://redis").unwrap()) Ī lot of libraries are sync (diesel is the one we use) and likely won't change anytime soon. My preferred solution would be to add a set method on the SystemRegistry like:.The main disadvantage is you now need to await the send call to first get the address of the sync actor and then await again to send a message to it. Alternatively you could switch from Actix for a thread-per-request HTTP server library like Iron or Rouille. await to the end of your redis call (modulo any differences between the two library's APIs). actixrt::main marked our main async function as to be executed in actix runtime. As you will already be inside an async function it should be as simple as tacking on a. It is quite elegant but the gist is old and not working anymore. Aug 02, while Rusts async/await is a lot of joy from a users POV. One possible solution is to have an actor to keep track of them (suggested on stackoverflow).This is annoying if you rely mostly on the registry but have a few sync actors for database calls for exemple. The way to set up a lambda handler is to provide either an async function or a struct that implements the Handler trait.
Thus you need another system to keep track of the sync actors and their addresses. Getting actix-web to run using netlifylambdahttp was very hard and probably the most frustrating thing Ive done in Rust so far. Current BehaviorĬurrently the SystemRegistry can only have actors with a Context. As Actix Web is nearing its inevitable 1.0 release, I thought it would be a great time to build something with it. This time were going to take what weve built on, and serve it as an HTTP API call.
