Enum GestureEvent 

#[non_exhaustive]
pub enum GestureEvent {
    Down {
        at: Point,
        pointer_id: i32,
    },
    Move {
        at: Point,
        pointer_id: i32,
    },
    Up {
        at: Point,
        pointer_id: i32,
    },
    Hold {
        pointer_id: i32,
    },
    Cancel,
}

An input to the machine.

Non-exhaustive because the gesture vocabulary provably grows (Hold arrived in 2.5); feed events in freely, but never match this exhaustively - treat unknown inputs as inert, like the machine does.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Down

Pointer pressed.

Fields

at: Point

pointer_id: i32

Move

Pointer moved.

Fields

at: Point

pointer_id: i32

Up

Pointer released.

Fields

at: Point

pointer_id: i32

Hold

The press’s hold timer elapsed while the pointer stayed put: a long-press. Promotes a matching GesturePhase::Pressed straight to a drag; inert in every other phase, so a stale timer firing after the gesture already resolved is harmless.

Fields

pointer_id: i32

Cancel

The platform cancelled the gesture (pointercancel).
