type Context = WebsocketContext<Self>

Actor execution context type

pub fn started(&mut self, ctx: &mut Self::Context)

Called when an actor gets polled the first time.

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

Called after an actor is in Actor::Stopping state.

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

Called after an actor is stopped.

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

Start a new asynchronous actor, returning its address.

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

Construct and start a new asynchronous actor, returning its address.

pub fn start_in_arbiter<F>(arb: &Arbiter, f: F) -> Addr<Self> where
    F: FnOnce(&mut Context<Self>) -> Self + Send + 'static,
    Self: Actor<Context = Context<Self>>, 

Start new actor in arbiter's thread.

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

Start a new asynchronous actor given a Context.

impl<Query, Mutation, Subscription> StreamHandler<Result<Message, ProtocolError>> for WSSubscription<Query, Mutation, Subscription> where
    Query: ObjectType + Sync + Send + 'static,
    Mutation: ObjectType + Sync + Send + 'static,
    Subscription: SubscriptionType + Send + Sync + 'static, 

pub fn handle(
    &mut self,
    msg: Result<Message, ProtocolError>,
    ctx: &mut Self::Context
)

Method is called for every message received by this Actor

pub fn started(&mut self, ctx: &mut Self::Context)

Method is called when stream get polled first time.

pub fn finished(&mut self, ctx: &mut Self::Context)

Method is called when stream finishes.

pub fn add_stream<S>(fut: S, ctx: &mut Self::Context) -> SpawnHandle where
    I: 'static,
    S: Stream<Item = I> + 'static,
    Self::Context: AsyncContext<Self>, 

This method register stream to an actor context and allows to handle Stream in similar way as normal actor messages.
