Implementations

impl Rule

pub fn defined_vars(&self) -> RapidSet<&str>

pub fn verify_util(&self) -> Result<(), RuleSerializeError>

check if util rules used are defined

Trait Implementations

impl Clone for Rule

fn clone(&self) -> Rule

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Rule

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Rule

Rule matches nothing by default. In Math jargon, Rule is vacuously false.

fn default() -> Self

Returns the “default value” for a type.

impl Matcher for Rule

fn match_node_with_env<'tree, D: Doc>( &self, node: Node<'tree, D>, env: &mut Cow<'_, MetaVarEnv<'tree, D>>, ) -> Option<Node<'tree, D>>

Attempt to match a node, updating the meta-variable environment.

fn potential_kinds(&self) -> Option<BitSet>

Provide a hint about which node types this matcher can match.

fn get_match_len<D>(&self, _node: Node<'_, D>) -> Option<usize>

where D: Doc,

Determine how much of a matched node should be replaced.
