Implementations

impl Catcode

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

a debug-friendly name

pub fn name_sym(self) -> SymStr

SymStr form of name() — each variant caches its interned symbol via pin!. Used by Token::get_cs_name / pin_cs_name to avoid a per-call pin_static hash probe (fires on every primitive-token definition lookup).

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

a \meaning-friendly name

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

a short name helpful for Token debugging

pub fn is_primitive(self) -> bool

TeX-primitive codes

pub fn is_executable(self) -> bool

Catcodes with associated primitives

pub fn is_neutralizable(self) -> bool

Catcodes which can be neutralized

pub fn is_active_or_cs(self) -> bool

Shorthand to match the “active” and “command sequence” catcodes

pub fn is_absorbable(self) -> bool

Tokens which can be absorbed without side-effects

pub fn is_gullet_holdable(self) -> bool

Gullet can only hold comment and marker tokens

pub fn is_balanced_interesting(self) -> bool

Catcodes that are of note for balanced reads.
