Trait ActiveRelationSource 

pub trait ActiveRelationSource: Send + Sync {

    // Required methods
    fn active_relations_for_subject<'a>(

}

Async read-side boundary for active relation state.

Prefer generic callers such as S: ActiveRelationSource for library and adapter code. Use DynActiveRelationSource only where application composition needs runtime erasure.

Required Associated Types

type Error: Error + Send + Sync + 'static

Source-specific error type.

Required Methods

fn active_relations_for_subject<'a>( &'a self, subject: &'a SubjectRef, ) -> impl Future<Output = ProviderResult<Vec<ActiveRelation>, Self::Error>> + Send + 'a

Finds active relation memberships for a subject.

fn active_relations_for_subject_by_ids<'a>( &'a self, subject: &'a SubjectRef, relation_ids: &'a [RelationId], ) -> impl Future<Output = ProviderResult<Vec<ActiveRelation>, Self::Error>> + Send + 'a

Finds active relation memberships for a subject, filtered by relation ids.

fn active_relations_for_subject_by_keys<'a>( &'a self, subject: &'a SubjectRef, keys: &'a [RelationKey], ) -> impl Future<Output = ProviderResult<Vec<ActiveRelation>, Self::Error>> + Send + 'a

Finds active relation memberships for a subject, filtered by relation keys.

Dyn Compatibility

This trait is not dyn compatible.

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