Xactor is a rust actors framework based on async-std

Documentation

• GitHub repository
• Cargo package
• Minimum supported Rust version: 1.39 or later

Features

• Async actors.
• Actor communication in a local context.
• Using Futures for asynchronous message handling.
• Typed messages (No Any type). Generic messages are allowed.

Examples

use xactor::*;

#[message(result = "String")]
struct ToUppercase(String);

struct MyActor;

impl Actor for MyActor {}

#[async_trait::async_trait]
impl Handler<ToUppercase> for MyActor {
    async fn handle(&mut self, _ctx: &Context<Self>, msg: ToUppercase) -> String {
        msg.0.to_uppercase()
    }
}

#[xactor::main]
async fn main() -> Result<()> {
    // Start actor and get its address
    let mut addr = MyActor.start().await;

    // Send message `ToUppercase` to actor via addr
    let res = addr.call(ToUppercase("lowercase".to_string())).await?;
    assert_eq!(res, "LOWERCASE");
    Ok(())
}

Installation

Xactor require async-trait on useland

With cargo add installed run:

$ cargo add xactor
$ cargo add async-trait

We also provide a set of "tokio-runtime" features instead of async-std. to use it you need activate feautre: runtime-tokio and desable default.

You can edit your Cargo.toml has following:

xactor = { version = "x.x.x", features = ["runtime-tokio"], default-features = false }
