Struct ActionRegistry 

pub struct ActionRegistry { /* private fields */ }

Action registry for a node

Maintains bidirectional mapping between action names and IDs, and dispatches to appropriate handlers.

Implementations

impl ActionRegistry

pub fn from_manifest(manifest: NodeManifest) -> Self

Create registry from node manifest

Registers standard actions (IDs 0-2) and custom actions (IDs 100+).

Arguments

• manifest - Node manifest containing action definitions

Returns

• Self - Initialized action registry

pub fn trigger( &self, name: &str, ctx: &ActionContext<'_>, seed: u64, ) -> Result<Vec<ParamUpdate>, ActionError>

Trigger action by name (UI path)

Looks up action ID by name and dispatches.

Arguments

• name - Action name (e.g., “reset”, “randomize”)
• ctx - Action context with current parameter state
• seed - Random seed for randomize action

Returns

• Ok(Vec<ParamUpdate>) - Parameter updates to apply
• Err(ActionError) - Action not found or execution failed

pub fn execute( &self, id: ActionId, ctx: &ActionContext<'_>, seed: u64, ) -> Result<Vec<ParamUpdate>, ActionError>

Execute action by numeric ID (fast path)

Directly dispatches to handler without name lookup.

Arguments

• id - Numeric action ID
• ctx - Action context with current parameter state
• seed - Random seed for randomize action

Returns

• Ok(Vec<ParamUpdate>) - Parameter updates to apply
• Err(ActionError) - Invalid ID or execution failed

pub fn get_id(&self, name: &str) -> Option<ActionId>

Get action ID by name (for debugging)

pub fn action_count(&self) -> usize

Get action count (standard + custom)

pub fn is_standard(&self, id: ActionId) -> bool

Check if action is standard (built-in)
