Durable Entity in Rust

entity.rs

use serde::{Deserialize, Serialize};

#[derive(Serialize, Deserialize)]
struct Counter {
    value: i32,
}

#[entity(type = "counter")]
impl Counter {
    pub fn add(&mut self, amount: i32) {
        self.value += amount;
    }

    #[operation(name = "clear")]
    pub fn reset(&mut self) {
        self.value = 0;
    }

    pub fn get(&self) -> i32 {
        self.value
    }
}

The default entity type will be the name of the implementing type (use the type argument to override).

All public methods will be operations with a default name of the method name (use the operation attribute to override).
