A rule category (a “family” in the docs). Closed set: adding one is a deliberate edit here plus a title/slug review, not an accidental string.

Implementations

impl Category

pub const ALL: [Category; 13]

Every category, in display order.

pub fn all() -> &'static [Category]

All categories, in display order.

pub fn title(self) -> &'static str

The display title, matching the ## heading in docs/rules.md exactly.

pub fn slug(self) -> &'static str

The URL slug. Must equal docs_export::slugify(self.title()) (gated).

pub fn order(self) -> usize

Zero-based display position (index into Category::ALL).

Exhaustive match on purpose: adding a variant is a compile error here (as in title/slug), and the order() == ALL index test guards these indices against a reorder of ALL. No panic path, unlike ALL.position(..).unwrap().

pub fn from_title(title: &str) -> Option<Category>

Parse a category from its display title (the form used on a **Categories:** line). Case- and surrounding-whitespace-sensitive on the canonical title.

pub fn from_slug(slug: &str) -> Option<Category>

Parse a category from its URL slug.

Trait Implementations
