Module date_time_edit 

DateTimeEdit — single unified control for picking a DateTime.

Visually one widget: a single bordered frame containing a date TextInputField half, a small painted separator, a time TextInputField half, and a trailing built-in calendar button that opens a Calendar popover anchored below the wrapper. Backed by Signal<Option<DateTime>>.

Why one frame?

Two adjacent DateEdit + TimeEdit (one frame each) visually read as two separate fields that happen to be next to each other. A single frame says “this is one moment in time” — same affordance the user is used to from booking sites, calendar apps, and form builders.

Behaviour

• Two text halves — date pattern on the left (locale-derived strftime subset), time pattern on the right (24h or 12h, with or without seconds). Each half carries its own input mask, validator, and segment-stepping (Up/Down on the focused segment).
• Painted separator — a thin middle-dot glyph (·), no text. Visual only; AT users see the wrapper’s Role::DateTimeInput. The separator can be replaced with a custom string via separator (rendered as styled secondary text).
• One trailing calendar button — Int UI IconButton::embedded() with the calendar glyph. Opens a single popover hosting Calendar::single bound to the date half. Picking a cell commits the date and closes the popover; the time half retains whatever the user typed.
• One frame — focus-aware border (BorderRole::Focused while any half holds focus, otherwise Default), validation-aware border (Error for Invalid, Focused for Corrected).
• One validation strip below the frame — composed feedback from both halves (worse of the two wins).

Accessibility

• Container — Role::DateTimeInput with set_value formatted as YYYY-MM-DDTHH:MM:SS (ISO 8601 datetime).
• Each TextInputField keeps its own Role::TextInput AT node; the wrapper’s Role::DateTimeInput provides the datetime semantics.

// Requires ctx.signal() — shown as ignore per convention.
use teksilo_widgets::date_time_edit::{DateTimeEdit, SecondsMode};

let datetime = ctx.signal(None);
let _w = DateTimeEdit::new(datetime.clone())
    .seconds(SecondsMode::Hidden)
    .on_value_changed(|dt, _ctx| println!("{dt:?}"));
