Struct DatePickerState 

pub struct DatePickerState { /* private fields */ }

Holds the current selection and display state for a date picker.

is_selectable_date and is_selectable_year are optional predicates. None means every date or year is selectable. A date is selectable only when it is inside the year range and both predicates allow it.

[CallbackWith] must be created during a component build, so these setters have to be called from inside a #[tessera] component. Closures passed to date_picker are turned into callbacks at that component boundary.

Implementations

impl DatePickerState

pub fn new( initial_selected_date: Option<CalendarDate>, initial_displayed_month: Option<YearMonth>, year_range: RangeInclusive<i32>, is_selectable_date: Option<CallbackWith<CalendarDate, bool>>, is_selectable_year: Option<CallbackWith<i32, bool>>, display_mode: DatePickerDisplayMode, ) -> Self

Creates a date picker state.

is_selectable_date and is_selectable_year are optional. None allows every date or year. When a callback is supplied, it must already have been created during a component build.

pub fn selected_date(&self) -> Option<CalendarDate>

Returns the selected date, if any.

pub fn displayed_month(&self) -> YearMonth

Returns the month currently displayed by the picker.

pub fn display_mode(&self) -> DatePickerDisplayMode

Returns the display mode.

pub fn year_range(&self) -> &RangeInclusive<i32>

Returns the year range allowed by this picker.

pub fn is_selectable_date(&self) -> Option<CallbackWith<CalendarDate, bool>>

Returns the date predicate, if one is set.

None means every date is selectable, subject to the year range and year predicate.

pub fn is_selectable_year(&self) -> Option<CallbackWith<i32, bool>>

Returns the year predicate, if one is set.

None means every year is selectable, subject to the year range.

pub fn set_selected_date(&mut self, date: CalendarDate) -> bool

Sets the selected date if it is allowed.

pub fn clear_selected_date(&mut self)

Clears the selected date.

pub fn set_displayed_month(&mut self, month: YearMonth)

Updates the displayed month, clamped to the year range.

pub fn next_month(&mut self)

Moves the displayed month forward by one, staying within the year range.

pub fn previous_month(&mut self)

Moves the displayed month backward by one, staying within the year range.

pub fn set_display_mode(&mut self, mode: DatePickerDisplayMode)

Updates the display mode.

pub fn toggle_display_mode(&mut self)

Toggles between picker and input modes.

pub fn set_year_range(&mut self, year_range: RangeInclusive<i32>)

Updates the allowed year range.

pub fn set_is_selectable_date( &mut self, is_selectable_date: Option<CallbackWith<CalendarDate, bool>>, )

Updates the date predicate.

None means every date is selectable. A callback must be created during a component build, so call this setter from inside a #[tessera] component.

pub fn set_is_selectable_year( &mut self, is_selectable_year: Option<CallbackWith<i32, bool>>, )

Updates the year predicate.

None means every year is selectable. A callback must be created during a component build, so call this setter from inside a #[tessera] component.

impl Default for DatePickerState

fn default() -> Self
