Enum kas::event::IsUsed

source ·
pub enum IsUsed {
    Unused,
    Used,
}
Expand description

Return type of event-handling methods

This type is convertible to/from bool and supports the expected bit-wise OR operator (a | b, *a |= b).

The type also implements negation with output type bool, thus allowing if is_used.into() { ... } and if !is_used { ... }. An implementation of Deref would be preferred, but the trait can only output a reference.

Variants§

§

Unused

Event was unused

Unused events may be used by a parent/ancestor widget or passed to another handler until used.

§

Used

Event is used, no other result
