Enum RegistryRequest

pub enum RegistryRequest {
    RegisterGlobalViewTreeWatcher {
        watcher: ServerEnd<ViewTreeWatcherMarker>,
        responder: RegistryRegisterGlobalViewTreeWatcherResponder,
    },
}

*** ONLY FOR USE IN TESTS *** This is a sensitive protocol. It provides unlimited access to the global view tree. Hand it out ONLY to test components.

Production uses should obtain observation protocols through a graphics factory function (see |fuchsia.ui.composition.ViewBoundProtocols|), which securely ties observation protocols to a specific view client.

Variants

RegisterGlobalViewTreeWatcher

Sets up a channel for receiving global view geometry.

This method may be called multiple times to obtain multiple geometry ViewTreeWatchers, if necesary. However, typical test usage is to obtain just one geometry ViewTreeWatcher in the test component.

Flow control. The caller is allowed at most one in-flight call at a time. Subsequent calls must wait until the acknowledgment returns. Non-compliance results in channel closure.

Client can freely disconnect this Registry endpoint after this method returns.

Fields

watcher: ServerEnd<ViewTreeWatcherMarker>
