[−]Struct actix_web::actix::actix::dev::System
System is an actor which manages runtime.
Before starting any actix's actors, System
actor has to be created and
started with System::run()
call. This method creates new Arbiter
in
current thread and starts System
actor.
Examples
extern crate actix; use actix::prelude::*; use std::time::Duration; struct Timer { dur: Duration, } impl Actor for Timer { type Context = Context<Self>; // stop system after `self.dur` seconds fn started(&mut self, ctx: &mut Context<Self>) { ctx.run_later(self.dur, |act, ctx| { // Stop current running system. System::current().stop(); }); } } fn main() { // initialize system and run it. // This function blocks current thread let code = System::run(|| { // Start `Timer` actor Timer { dur: Duration::new(0, 1), }.start(); }); std::process::exit(code); }
Methods
impl System
impl System
pub fn builder() -> Builder
pub fn builder() -> Builder
Build a new system with a customized tokio runtime.
This allows to customize the runtime. See struct level docs on
Builder
for more information.
pub fn new<T>(name: T) -> SystemRunner where
T: Into<String>,
pub fn new<T>(name: T) -> SystemRunner where
T: Into<String>,
Create new system.
This method panics if it can not create tokio runtime
pub fn current() -> System
pub fn current() -> System
Get current running system.
pub fn with_current<F, R>(f: F) -> R where
F: FnOnce(&System) -> R,
pub fn with_current<F, R>(f: F) -> R where
F: FnOnce(&System) -> R,
Execute function with system reference.
pub fn stop(&self)
pub fn stop(&self)
Stop the system
pub fn arbiter(&self) -> &Addr<Arbiter>
pub fn arbiter(&self) -> &Addr<Arbiter>
System arbiter
pub fn registry(&self) -> &SystemRegistry
pub fn registry(&self) -> &SystemRegistry
Get current system registry.
pub fn run<F>(f: F) -> i32 where
F: FnOnce() + 'static,
pub fn run<F>(f: F) -> i32 where
F: FnOnce() + 'static,
This function will start tokio runtime and will finish once the
System::stop()
message get called.
Function f
get called within tokio runtime context.
