Trait Behavior 

pub trait Behavior {
    type Addr: Address;
    type Msg;
    type Event: UserEvent<Addr = Self::Addr, Message = Self::Msg>;
    type Sends: SendAlgebra;
    type Ph;
    type Error;
    type Birth: BirthMode;

    // Required method
    fn transition(
        &mut self,
        _turn: ActiveTurn,
        event: Self::Event,
    ) -> BehaviorActed<Self>;

    // Provided method
    fn init(&mut self, _turn: InitializationTurn) -> BehaviorActed<Self>
       where Self: Sized { ... }
}

A composed pure behavior. Event is the complete accepted protocol; every successful transition returns the declared Actions value.

Required Associated Types

type Addr: Address

type Msg

type Event: UserEvent<Addr = Self::Addr, Message = Self::Msg>

type Sends: SendAlgebra

type Ph

type Error

type Birth: BirthMode

Required Methods

fn transition( &mut self, _turn: ActiveTurn, event: Self::Event, ) -> BehaviorActed<Self>

Fold exactly one event into explicit actions and the next behavior.

Errors

Returns the behavior’s declared controlled transition failure.

Provided Methods

fn init(&mut self, _turn: InitializationTurn) -> BehaviorActed<Self>

where Self: Sized,

Produce initialization actions before the first event is accepted.

Errors

Returns the behavior’s declared controlled initialization failure.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
