Trait Implementations

impl Actor for DefaultSignalsHandler

type Context = Context<DefaultSignalsHandler>

Actor execution context type

fn started(&mut self, ctx: &mut <DefaultSignalsHandler as Actor>::Context)

Method is called when actor get polled first time.

fn stopping(&mut self, ctx: &mut Self::Context) -> Running

Method is called after an actor is in Actor::Stopping state. There could be several reasons for stopping. Context::stop get called by the actor itself. All addresses to current actor get dropped and no more evented objects left in the context.

fn stopped(&mut self, ctx: &mut Self::Context)

Method is called after an actor is stopped, it can be used to perform any needed cleanup work or spawning more actors. This is final state, after this call actor get dropped.

fn start(self) -> Addr<Self>where
    Self: Actor<Context = Context<Self>>,

Start new asynchronous actor, returns address of newly created actor.

fn start_default() -> Addr<Self>where
    Self: Actor<Context = Context<Self>> + Default,

Start new asynchronous actor, returns address of newly created actor.

fn create<F>(f: F) -> Addr<Self>where
    Self: Actor<Context = Context<Self>>,
    F: 'static + FnOnce(&mut Context<Self>) -> Self,

Use create method, if you need Context object during actor initialization.

impl Default for DefaultSignalsHandler

fn default() -> DefaultSignalsHandler

Returns the “default value” for a type.

impl Handler<Signal> for DefaultSignalsHandler

Handle SIGINT, SIGTERM, SIGQUIT signals and send SystemExit(0) message to System actor.

type Result = ()

The type of value that this handle will return

fn handle(
    &mut self,
    msg: Signal,
    _: &mut <DefaultSignalsHandler as Actor>::Context
)

Method is called for every message received by this Actor
