Enum DispatchPhase 

pub enum DispatchPhase {
    Bubble,
    Capture,
}

The two passes an event makes through the element tree.

Each event is offered first in the capture phase and then in the bubble phase. Listeners receive the phase as an argument, so one listener can check which pass it is in. See input dispatch.

Variants

Bubble

The bubble phase, which runs after capture.

Mouse listeners run front to back, and key listeners run from the focused element up to the root. Most listeners you register belong in this phase.

Capture

The capture phase, which runs before bubble.

Mouse listeners run back to front, and key listeners run from the root down to the focused element. Use it for special cases, such as clearing a pressed state when a click starts outside an element. If you stop propagation here, the bubble phase never runs for that event.
