1//! # Boolean value
2//!
3//! The decoded boolean value kind.
4//!
5//! Backs the boolean-valued properties and parameters (RFC 5545 3.3.2): the
6//! case-insensitive tokens `TRUE` and `FALSE`. The value is kept as its raw
7//! text so the original casing round-trips; use [`IcalBoolean::is_true`] to
8//! read it as a `bool`. Pure data, no escaping; the owning property's wire name
9//! lives on [`crate::prop::IcalProp::name`].
