Struct FunctionRegistry 

pub struct FunctionRegistry { /* private fields */ }

Keeps a mapping from FunctionType to stateful functions. Use this together with a Transport to serve stateful functions.

Use register_fn() to register functions before handing the registry over to a Transport for serving.

Implementations

impl FunctionRegistry

pub fn new() -> FunctionRegistry

Creates a new empty FunctionRegistry.

pub fn register_fn<I: Message, F: Fn(Context<'_>, I) -> Effects + Send + 'static>( &mut self, function_type: FunctionType, function: F, )

Registers the given function under the function_type.

pub fn invoke( &self, target_function: FunctionType, context: Context<'_>, message: Any, ) -> Result<Effects, Error>

Invokes the function that is registered for the given FunctionType. This will return Err if no function is registered under the given type.
