Enum ControllerRequest 

pub enum ControllerRequest {
    Start {
        args: StartChildArgs,
        execution_controller: ServerEnd<ExecutionControllerMarker>,
        responder: ControllerStartResponder,
    },
    IsStarted {
        responder: ControllerIsStartedResponder,
    },
    GetExposedDictionary {
        responder: ControllerGetExposedDictionaryResponder,
    },
    Destroy {
        responder: ControllerDestroyResponder,
    },
    #[non_exhaustive]
    _UnknownMethod {
        ordinal: u64,
        control_handle: ControllerControlHandle,
        method_type: MethodType,
    },
}

A protocol used to operate on a component.

One may get access to a Controller when creating a component with the Realm.CreateChild method. You may also obtain a Controller for an existing child component with the Realm.OpenController method.

Variants

Start

Start the component, optionally providing additional handles to be given to the component. Returns INSTANCE_ALREADY_RUNNING if the instance is currently running.

Fields

args: StartChildArgs

execution_controller: ServerEnd<ExecutionControllerMarker>

responder: ControllerStartResponder

IsStarted

Returns true if this instance is currently running.

Fields

responder: ControllerIsStartedResponder

GetExposedDictionary

Returns the dictionary containing the component’s exposed capabilities.

Fields

responder: ControllerGetExposedDictionaryResponder

Destroy

Destroys this component. When this method returns, the component is either destroyed or in the case of an error no destruction happened.

Errors:

• ACCESS_DENIED: Destruction of this component is not allowed. Currently, this can happen if the component is a static child of its parent.
• INTERNAL: Something prevented destruction from succeeding – component manager’s logs will contain more detail.

Fields

responder: ControllerDestroyResponder

#[non_exhaustive]

_UnknownMethod

An interaction was received which does not match any known method.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

ordinal: u64

Ordinal of the method that was called.

control_handle: ControllerControlHandle

method_type: MethodType
