Trait CallBridge 

pub trait CallBridge {
    // Required methods
    fn arora_call(&mut self, call: Call) -> Result<CallResult, CallError>;
    fn arora_register_callable(
        &mut self,
        callable: Rc<dyn Callable>,
    ) -> CallableId;
    fn arora_unregister_callable(&mut self, callable_id: &CallableId);
    fn arora_call_indirect(
        &mut self,
        callable_id: &CallableId,
    ) -> Result<Value, CallError>;
}

The interface a module uses to call back into its host (the engine, or a mock in tests). It lives here, in the interface layer, so module-shaped libraries can make host calls without depending on the engine crate.

Required Methods

fn arora_call(&mut self, call: Call) -> Result<CallResult, CallError>

Dispatch call to the module it names: the call is the full description of the invocation, and one naming no module is refused.

fn arora_register_callable(&mut self, callable: Rc<dyn Callable>) -> CallableId

Registers the given function in the executor and associates it to an identifier generated on the fly. The function is made available to every module by calling arora_dispatch_indirect(id: u64) -> Value.

fn arora_unregister_callable(&mut self, callable_id: &CallableId)

Unregisters the function associated to the given identifier.

fn arora_call_indirect( &mut self, callable_id: &CallableId, ) -> Result<Value, CallError>

Calls a callable that was registered.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
