SelectionEngine

class SelectionEngine(mode: SelectionMode, bounds: ClosedRange<LocalDate>? = null, disabled: DisabledDates = DisabledDates.None)

Pure selection state machine. click never mutates; it returns the new Selection plus any violation events. Bounds and disabled dates are checked before mode-specific handling, matching the original library's out-of-range and OnCalendarInterceptListener behavior.

fun click(current: Selection, date: LocalDate): SelectionResult

replace
