Enum RegistryRequest

pub enum RegistryRequest {
    WatchDevicesAdded {
        responder: RegistryWatchDevicesAddedResponder,
    },
    WatchDeviceRemoved {
        responder: RegistryWatchDeviceRemovedResponder,
    },
    CreateObserver {
        payload: RegistryCreateObserverRequest,
        responder: RegistryCreateObserverResponder,
    },
    _UnknownMethod {
        ordinal: u64,
        control_handle: RegistryControlHandle,
        method_type: MethodType,
    },
}

Registry instances notify clients as devices arrive and depart, and they create observers (see Observer) that notify of more detailed state changes.

Variants

WatchDevicesAdded

Register for notification when one or more devices are added. The devices vector will always contain at least one Info entry.

Fields

responder: RegistryWatchDevicesAddedResponder

WatchDeviceRemoved

Register for notification when an (active, added) device is removed. Because the method only notifies of one removal, upon completion it should immediately be re-called, in case other removals have occurred. Calls to this method will pend until the removal of a device that was included in a previous WatchDevicesAdded response.

Fields

responder: RegistryWatchDeviceRemovedResponder

CreateObserver

Request an Observer for the specified device.

Fields

payload: RegistryCreateObserverRequest

responder: RegistryCreateObserverResponder

_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: RegistryControlHandle

method_type: MethodType
