Trait EventExt

pub trait EventExt:
    Event
    + Sized
    + 'static {
    // Provided methods
    fn take_handler() -> Box<Handler<Self>> { ... }
    fn replace_handler<F: FnMut(&Self) + Sync + Send + 'static>(
        f: F,
    ) -> Box<Handler<Self>> { ... }
    fn update_handler<F: FnMut(&Self) + Sync + Send + 'static>(f: F) { ... }
}

Available on crate feature unstable only.

Extension trait for setting handlers for an event.

Register a new event handler like:

event::ApStaConnected::update_handler(|_cs, event| {
    new_handler(event);
})

Stability

This API is marked as unstable and is only available when the unstable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.

Provided Methods

fn take_handler() -> Box<Handler<Self>>

Get the handler for this event, replacing it with the default handler.

fn replace_handler<F: FnMut(&Self) + Sync + Send + 'static>( f: F, ) -> Box<Handler<Self>>

Set the handler for this event, returning the old handler.

fn update_handler<F: FnMut(&Self) + Sync + Send + 'static>(f: F)

Atomic combination of Self::take_handler and Self::replace_handler. Use this to add a new handler which runs after the previously registered handlers.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
