1//! `serde` support for [`Identifier`], compiled only with the `serde` feature.
2//!
3//! An identifier serializes as its canonical token string (for example `"+K^"`)
4//! and deserializes by parsing that string. The implementation is `no_std`:
5//! serialization borrows a stack buffer and deserialization borrows the input.
