This is a data structure for registering delegates associated with prediction key rejection and replicated state 'catching up'.

Generic numerical value in the form Value * Curve[Level]

Scope object that indicates when a gameplay effect is being applied

Used to stop us from removing abilities from an ability system component while we're iterating through the abilities

FScopedActiveGameplayEffectLock Provides a mechanism for locking the active gameplay effect list while possibly invoking callbacks into gamecode.

Allows us to batch all aggregator OnDirty calls within a scope.

FScopedGameplayCueSendContext Add this around code that sends multiple gameplay cues to allow grouping them into a smalkler number of cues for more efficient networking

A structure for allowing scoped prediction windows.

Used to stop us from canceling or ending an ability while we're iterating through its gameplay targets
