Struct DefaultTopic 

pub struct DefaultTopic;

Unit topic for systems that don’t need topic-based routing.

Since every event maps to the same single topic, actors subscribing to DefaultTopic will receive all events. This is the default generic parameter on Supervisor, keeping simple setups free of a custom topic type.

Examples

use maiko::{Supervisor, DefaultTopic};
let mut sup = Supervisor::<MyEvent>::default();
sup.add_actor("actor", |ctx| MyActor { ctx }, &[DefaultTopic])?;

Trait Implementations

impl Clone for DefaultTopic

fn clone(&self) -> DefaultTopic

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DefaultTopic

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for DefaultTopic

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for DefaultTopic

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DefaultTopic

fn eq(&self, other: &DefaultTopic) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
