Required Associated Types

type Qualifier: QualifierFlag

Provided Methods

fn stream_stat( &self, entity: Entity, qualifier: &QualifierQuery<Self::Qualifier>, stat_value: &mut StatValuePair, querier: Querier<'_, Self::Qualifier>, )

fn stream_relation( &self, other: &Self, entity: Entity, target: Entity, qualifier: &QualifierQuery<Self::Qualifier>, stat_value: &mut StatValuePair, querier: Querier<'_, Self::Qualifier>, )

fn has_attribute(&self, entity: Entity, attribute: Attribute<'_>) -> bool

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
