Crate absinthe 

Absinthe

Absinthe is a library that allows you to create actors in Rust, and communicate with them using async messages. It provides Actor Model primitives, and a super-macro to easily create actors. Just write your Rust code, and Absinthe will handle the rest.

Features

• Actor Model - Absinthe provides an Actor trait, and a super-macro to easily create actors.
• Async Messaging - Absinthe provides a Courier trait, and macros to easily send messages to actors.
• Async Tasks - Absinthe provides a spawn function to spawn actors as async tasks.
• Async Channels - Absinthe uses async channels to communicate with actors.
• Actor Functions - actor! macro can be used to ‘actorize’ functions, implementing the Actor trait and spawning constructors.
• Actor Structs - actor! macro can be used to ‘actorize’ structs, implementing the Actor trait and message routing.

Example

use absinthe::prelude::*;
 
actor! {
    async fn add(a: u32, b: u32) -> u32 {
       a + b
   }
}
 
#[tokio::main]
async fn main() {
   let adder = add();
   assert_eq!(send!(adder, 1, 2).await, 3);
}

Modules

actor

Actor traits & primitives.

msg

Message traits & primitives.

prelude

Absinthe prelude, providing a good starter pack to start writing actors.

Macros

actor

Provides the actor! macro, which ‘actorizes’ functions & structs. Also provides messaging macros, such as send! and notify! Create an actor. Can be used on a struct or a function. If actorizing a struct, the struct must have an impl block. The impl block must have the same name as the struct.

notify

Provides the actor! macro, which ‘actorizes’ functions & structs. Also provides messaging macros, such as send! and notify! Send a message to an actor, and don’t wait for a response.

send

Provides the actor! macro, which ‘actorizes’ functions & structs. Also provides messaging macros, such as send! and notify! Send a message to an actor, and wait for a response.
