//! # Boolean value
//!
//! The decoded boolean value kind.
//!
//! Backs the boolean-valued properties and parameters (RFC 5545 3.3.2): the
//! case-insensitive tokens `TRUE` and `FALSE`. The value is kept as its raw
//! text so the original casing round-trips; [`IcalBoolean::is_true`] reads it
//! as a `bool`.
