Struct ObservationRelationship 

pub struct ObservationRelationship<P: Protocol> { /* private fields */ }

Non-authorizing identity of one accepted protocol-indexed relationship.

The protocol brand cannot be changed even when the address is shared:

fn wrong_protocol<P, Q>(relationship: behavior_actors::ObservationRelationship<P>, outcome: Result<behavior_actors::Exit<Q::Addr>, behavior_actors::Crash>, at: std::time::Instant) -> behavior_actors::EstablishedObservation<Q>
where P: behavior::Protocol, Q: behavior::Protocol<Addr = P::Addr>, Q::Addr: behavior::RecipientAddress {
    behavior_actors::EstablishedObservation::Stopped { relationship, outcome, at }
}

A read-only relationship is not a cancellation permission:

fn permission<P: behavior::Protocol>(relationship: behavior_actors::ObservationRelationship<P>) -> behavior_actors::ObservationAuthority<P> {
    relationship
}

Same-protocol terminal reports and read-only identity transfer remain valid.

pub fn stopped<P, Q>(relationship: behavior_actors::ObservationRelationship<P>, outcome: Result<behavior_actors::Exit<P::Addr>, behavior_actors::Crash>, at: std::time::Instant) -> behavior_actors::EstablishedObservation<P>
where P: behavior::Protocol, Q: behavior::Protocol<Addr = P::Addr>, P::Addr: behavior::RecipientAddress {
    behavior_actors::EstablishedObservation::Stopped { relationship, outcome, at }
}

pub fn retained_relationship<P: behavior::Protocol>(relationship: behavior_actors::ObservationRelationship<P>) -> behavior_actors::ObservationRelationship<P> {
    relationship
}

Implementations

impl<P: Protocol> ObservationRelationship<P>

pub fn id(&self) -> ObservationId

pub fn identity(&self) -> &Arc<ObservationId>

Borrow the strong accepted identity for exact runtime membership checks.

Reading or cloning this Arc confers no cancellation permission and cannot reconstruct or rebrand a relationship.

Trait Implementations

impl<P: Protocol> Clone for ObservationRelationship<P>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<P: Protocol> Debug for ObservationRelationship<P>

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

Formats the value using the given formatter.

impl<P: Protocol> PartialEq for ObservationRelationship<P>

fn eq(&self, other: &Self) -> 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.
