Enum RawPointerEvent 

pub enum RawPointerEvent {
    Down {
        position: Point,
        button: PointerButton,
        modifiers: Modifiers,
        pointer: PointerInfo,
        time: EventTime,
    },
    Move {
        position: Point,
        pointer: PointerInfo,
        time: EventTime,
    },
    Up {
        position: Point,
        button: PointerButton,
        modifiers: Modifiers,
        pointer: PointerInfo,
        time: EventTime,
    },
    Cancel {
        position: Point,
        pointer: PointerInfo,
        reason: CancelReason,
        time: EventTime,
    },
}

Raw pointer events fed into gesture recognizers.

Every variant carries the PointerInfo that produced it and the EventTime the backend stamped it with, so a recognizer never has to ask which contact this is or when it happened — the two questions a per-contact, clock-free recognizer cannot answer for itself.

Variants

Down

Fields

position: Point

button: PointerButton

modifiers: Modifiers

pointer: PointerInfo

time: EventTime

Move

Fields

position: Point

pointer: PointerInfo

time: EventTime

Up

Fields

position: Point

button: PointerButton

modifiers: Modifiers

pointer: PointerInfo

time: EventTime

Cancel

The interaction was revoked rather than completed — the window lost focus, a modal opened over it, the OS took the pointer. Distinct from Up on purpose: an Up means the user finished, a Cancel means the system interrupted, and conflating them is how a drag ends up “dropped” wherever the pointer happened to be.

Fields

position: Point

pointer: PointerInfo

reason: CancelReason

time: EventTime
