//! Custom keywords for the `routes!` DSL.
//!
//! One responsibility: declare the identifiers the `routes!` parser treats as
//! keywords. They live in two groups so a route option named `get` could
//! never be confused with the `get` method keyword: [`option`] holds the
//! declaration/option keywords, [`method`] holds the HTTP method keywords.
/// Declaration-level and route-option keywords.
/// HTTP method keywords that open a route entry.
