//! `RankScoreKind::as_str` and `SearchSource::as_str` return the strings that
//! search results carry on the wire. Each variant's string is pinned here, in
//! the crate that defines the types.
//!
//! The `match` in each helper has no wildcard arm, so a new variant does not
//! compile until its wire string is written down in that helper.
