Struct DatePicker 

pub struct DatePicker(/* private fields */);

Pick a day from a month grid. Returns the Date.

use rich_interact::datetime::Date;
use rich_interact::headless::{self, Script};
use rich_interact::{DatePicker, Outcome};

let picker = DatePicker::new("Due").value(Date::new(2026, 10, 17));
let script = Script::new().keys("right down enter");
let (outcome, record) = headless::run(picker, script, 40, 14);
assert_eq!(outcome.unwrap(), Outcome::Done(Date::new(2026, 10, 25)));
assert_eq!(record.last_frame(), "? Due › 2026-10-25");

Implementations

impl DatePicker

pub fn new(prompt: impl Into<String>) -> DatePicker

pub fn theme(self, theme: Theme) -> Self

pub fn with_mouse(self, on: bool) -> Self

Report the mouse (#476): a click selects a day (a second click on it picks it) or focuses a time field, and the wheel turns the month or the focused field.

pub fn rebind(self, action: &str, keys: impl IntoIterator<Item = Key>) -> Self

Make keys do action (see date_keymap) on this picker only; no keys unbinds it.

pub fn today(self, today: Date) -> Self

The day marked as today and t goes to (default: today in UTC).

pub fn value(self, date: Date) -> Self

Start on this day.

pub fn default(self, date: Date) -> Self

Answer this day without a terminal and to an empty line, and start on it unless value says where to start.

pub fn min(self, date: Date) -> Self

The earliest day that can be picked.

pub fn max(self, date: Date) -> Self

The latest day that can be picked.

pub fn validate( self, check: impl Fn(Date) -> Result<(), String> + Send + Sync + 'static, ) -> Self

Refuse a day check returns an error for (a weekend, a holiday): Enter shows the error and waits.

pub fn selected(&self) -> Date

The day selected so far.

Trait Implementations

impl Component for DatePicker

fn focus_step(&mut self, forward: bool) -> bool

Tab inside: the next part, if there is one.

fn focus_enter(&mut self, forward: bool) -> bool

Tab from outside: the first part, or the last going back.

fn default_value(&self) -> Option<Date>

The default, unless the picker would refuse it: outside the range, or refused by the validator.

type Output = Date

fn start(&mut self, _context: &Context<'_>) -> Flow<Date>

Called once, before the component is first painted, with the terminal’s size: for work that needs it, such as rendering content at the width. Returning Done or Cancel finishes the component without waiting for an event. The default does nothing.

fn handle(&mut self, event: &Event, _context: &Context<'_>) -> Flow<Date>

Handle one event. Ctrl+C never arrives here: the event loop ends the component with Outcome::Interrupted.

fn render(&self, context: &Context<'_>) -> View

Render the current state.

fn mouse(&self) -> bool

Whether the component wants mouse events (#476): clicks, drags and the wheel. Off by default, since reporting the mouse takes text selection away from the terminal; a component turns it on when its caller opts in, and run then enables mouse reporting for the session.

fn keymap(&self) -> Keymap

The bindings this component has right now, for a help overlay, a shortcut list or status-bar hints to read (see keymap). A container’s include its focused child’s, before its own. The default declares none.

fn prompt( &mut self, io: &mut dyn LineIo, ) -> Result<Option<Date>, NotInteractive>

Ask for the value line by line, for when the terminal is not interactive and the policy asks for a prompt. The default says the component has no line-based form.

fn tick(&self) -> Option<Duration>

How often the component wants Event::Tick, for a spinner or a countdown. None (the default): never.

fn focusable(&self) -> bool

Whether the component takes focus in a container: Tab stops on it and keys go to it. The default: yes. A label, or a component that has finished, says no.
