Enum KeyResponse 

Source 
pub enum KeyResponse<Msg = Callback> {
    Ignored,
    Handled(Option<Msg>),
    Skip,
}
Expand description

A widget’s response to a key received during the leaf→root bubble (the focused one first, then its ancestors for as long as the result is Ignored).

Variants§

§

Ignored

Not concerned: the key keeps bubbling up.

§

Handled(Option<Msg>)

Consumed (with an optional message to emit): the bubbling stops.

§

Skip

Not consumed, but the bubbling stops, and no fallback is attempted.
