Enum SetupRequest

pub enum SetupRequest {
    GetViewRefs {
        responder: SetupGetViewRefsResponder,
    },
    WatchViewport {
        responder: SetupWatchViewportResponder,
    },
}

A service used by an input pipeline to set up pointer injection into Scenic. This should be implemented by the component that configures the scene (Root Presenter or Scene Manager).

Variants

GetViewRefs

Returns the viewrefs for injection authority (Config.context) and injection destination (Config.target).

This only returns when valid context and target views exist. Typically called just once.

Fields

responder: SetupGetViewRefsResponder

WatchViewport

Returns the current viewport. Follows the hanging get pattern.

The first call to this function will return the current viewport, whenever one exists. Subsequent calls will block until the viewport has been updated.

Flow control: There should only be one outstanding call to this function. The channel will be closed if an additional call to this function is made while a call is outstanding.

Fields

responder: SetupWatchViewportResponder
