Enum DeviceRequest

pub enum DeviceRequest {
    Inject {
        events: Vec<Event>,
        responder: DeviceInjectResponder,
    },
}

The channel for injecting pointer events into a target. The associated |Config| applies to injected pointer events.

A |Device| may inject pointer events into a target in the scene, but the dispatch of pointer events to UI clients within that target’s view tree will depend on the dispatch policy and the scene topology.

Variants

Inject

Injects events into a target.

Batching: The caller is expected to batch-inject all events that share the same timestamp (e.g., multiple finger samples). There may be multiple such batches per injection call.

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

Fields

events: Vec<Event>

responder: DeviceInjectResponder
