act-zero
An actor system for Rust, designed with several goals in mind:
- No boilerplate.
- Ergonomic.
- Supports standard trait-based static and dynamic polymorphism.
- Embraces async/await.
- Executor agnostic.
Very little code is required to get started:
use std::error::Error;
use futures::executor::LocalPool;
use act_zero::*;
struct SimpleGreeter {
number_of_greets: i32,
}
impl Actor for SimpleGreeter {}
impl SimpleGreeter {
async fn greet(&mut self, name: String) -> ActorResult<String> {
self.number_of_greets += 1;
Produces::ok(format!(
"Hello, {}. You are number {}!",
name, self.number_of_greets
))
}
}
fn main() -> Result<(), Box<dyn Error>> {
let mut pool = LocalPool::new();
let spawner = pool.spawner();
pool.run_until(async move {
let actor_ref = Addr::new(
&spawner,
SimpleGreeter {
number_of_greets: 0,
},
)?;
let greeting = call!(actor_ref.greet("John".into())).await?;
println!("{}", greeting);
let greeting = call!(actor_ref.greet("Emma".into())).await?;
println!("{}", greeting);
Ok(())
})
}
