Struct statefun::FunctionRegistry

pub struct FunctionRegistry { /* fields omitted */ }

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.

    &mut self,
    function_type: FunctionType,
    function: F
)

pub fn invoke(
    &self,
