Struct ModuleFactory 

pub struct ModuleFactory { /* private fields */ }

Registry that maps module type names to constructors.

Implementations

impl ModuleFactory

pub fn new() -> Self

Creates an empty module factory.

pub fn register(&mut self, ctor: impl ModuleConstructor + 'static)

Adds a typed constructor to the registry, keyed by its type name.

pub fn register_fn( &mut self, type_name: impl Into<String>, drain: Drain, make_handler: impl Fn(&str, &HashMap<String, ParamValue>, &ActorRef<CommandEnum>) -> Box<dyn FnMut(CommandEnum) + 'static> + Send + Sync + 'static, )

Register a closure-based constructor (handler: !Send).

make_handler receives module params and the graph handle, and returns the message handler closure. The factory calls it inside the drain thread, so the handler does not need Send.

pub fn register_fn_send( &mut self, type_name: impl Into<String>, drain: Drain, make_handler: impl Fn(&str, &HashMap<String, ParamValue>, &ActorRef<CommandEnum>) -> Box<dyn FnMut(CommandEnum) + Send + 'static> + Send + Sync + 'static, )

Register a closure-based constructor (handler: Send, for Drain::TokioTask).

The returned handler must be Send so it can be stored in a tokio future.

pub fn construct( &self, module: &ModuleDef, automaton_defs: &[AutomatonDef], system: &Arc<ActorSystem>, graph_ref: &ActorRef<CommandEnum>, ) -> Result<ActorRef<CommandEnum>, ModuleError>

Looks up a type name and constructs the corresponding module actor.

pub fn contains(&self, type_name: &str) -> bool

Checks whether a type name is registered.

pub fn len(&self) -> usize

Returns the number of registered module types.

pub fn is_empty(&self) -> bool

Returns true if no module types are registered.

Trait Implementations

impl Default for ModuleFactory

fn default() -> Self

Returns the “default value” for a type.
