Struct Registar 

pub struct Registar<M = ()> { /* private fields */ }

The Registar manages immutable runtime service registrations.

Implementations

impl<M> Registar<M>

pub fn give_form(&self) -> ServiceRegistrationForm<M>

Returns a capability to register one service.

pub async fn deregister( &self, service_binding: &ServiceBinding, ) -> Option<RegisteredService<M>>

Removes the registration for a final binding and returns it.

Returns None when no service is registered with that binding. A service that stops should remove its own registration, so the same binding can be registered again, for example when a stopped test environment restarts on a fixed port.

The registry is keyed by binding only, so this removes whichever registration holds that binding. Callers should pass only a binding they registered themselves.

pub async fn services(&self) -> Vec<RegisteredService<M>>

where M: Clone,

Returns a deterministic, side-effect-free snapshot of all services.

Results are ordered by protocol, then final socket address, never by insertion or hash-map iteration order.

pub async fn services_matching<F>( &self, predicate: F, ) -> Vec<RegisteredService<M>>

where M: Clone, F: Fn(&M) -> bool,

Returns a deterministic, side-effect-free metadata query result.

Trait Implementations

impl<M> Clone for Registar<M>

fn clone(&self) -> Self

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

Performs copy-assignment from source.

impl<M: Debug> Debug for Registar<M>

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

Formats the value using the given formatter.

impl<M> Default for Registar<M>

fn default() -> Self

Returns the “default value” for a type.
