1//! # RECUR value codec (RFC 5545 3.3.10)
2//!
3//! [`Codec`] for a recurrence rule. A RECUR value uses `;` to separate its
4//! rule parts (`FREQ=DAILY;COUNT=10`), which the generic node reads as separate
5//! components; they are rejoined with `;` on decode and written verbatim
6//! (unescaped, since RECUR is not TEXT) on encode.
