Event

Struct Event 

Source
pub struct Event<T> {
    pub args: T,
    /* private fields */
}
Expand description

Event wrapper passed to Pax event handlers.

Event<T> carries the typed event payload and shared cancellation state, allowing handlers to call prevent_default where the active chassis supports it.

Fields§

§args: T

The event-specific payload, for example Click or KeyDown.

Implementations§

Constructs an event wrapper around a raw payload.

Source

pub fn prevent_default(&self)
