Macro automate::methods

methods!() { /* proc-macro */ }

Parses a list of method listeners in the initialize method of a state struct.

Input should be the name of the struct followed by a colon and a comma-separated list of the listener functions that should be registered.

use automate::{methods, listener, Context, Error};
use automate::events::{Initializable, StatefulListener};
use automate::gateway::MessageCreateDispatch;

struct MessageCounter;

impl Initializable for MessageCounter {
    fn initialize() -> Vec<StatefulListener<Self>> {
        methods!(MessageCounter: say_hello, say_bye)
    }
}

impl MessageCounter {
    #[listener]
    async fn say_hello(&mut self, ctx: &Context, data: &MessageCreateDispatch) -> Result<(), Error> {
        println!("Hello!");
        Ok(())
    }

    #[listener]
    async fn say_bye(&mut self, ctx: &Context, data: &MessageCreateDispatch) -> Result<(), Error> {
        println!("Bye");
        Ok(())
    }
}
