Struct actix_web::actix::dev::msgs::Execute

pub struct Execute<I = (), E = ()>(_)
where
    I: 'static + Send,
    E: 'static + Send;

Execute function in arbiter’s thread

Arbiter` actor handles Execute message.

Example

use actix::prelude::*;

struct MyActor {
    addr: Addr<Arbiter>,
}

impl Actor for MyActor {
    type Context = Context<Self>;

    fn started(&mut self, ctx: &mut Context<Self>) {
        self.addr
            .do_send(actix::msgs::Execute::new(|| -> Result<(), ()> {
                // do something
                // ...
                Ok(())
            }));
    }
}
fn main() {}
