Struct BeforeMutationHooks 

pub struct BeforeMutationHooks {
    pub trigger_registry: TriggerRegistry,
    pub module_registry: HashMap<String, FunctionModule>,
    pub observer: Arc<FunctionObserver>,
}

Shared bundle of before-mutation state passed into AppState for handler access.

This is a lightweight, cloneable snapshot of the parts of FunctionsSubsystem that are needed on the hot path for before-mutation checks. It is extracted once at server startup and stored in AppState via an Arc.

Fields

trigger_registry: TriggerRegistry

Registry of all loaded triggers, keyed by trigger type and mutation name.

module_registry: HashMap<String, FunctionModule>

Loaded function modules keyed by function name.

observer: Arc<FunctionObserver>

Observer that dispatches events to the appropriate function runtime.
