Struct MatcherContext 

pub struct MatcherContext<'db> {
    pub captures: OrderedHashMap<SmolStrId<'db>, Vec<CapturedValue<'db>>>,
    pub placeholder_to_rep_id: OrderedHashMap<SmolStrId<'db>, RepetitionId>,
    pub current_repetition_stack: Vec<RepetitionId>,
    pub next_repetition_id: usize,
    pub repetition_indices: OrderedHashMap<RepetitionId, usize>,
    pub repetition_match_counts: OrderedHashMap<RepetitionId, usize>,
    pub repetition_operators: OrderedHashMap<RepetitionId, MacroRepetitionOperator<'db>>,
}

Context used during macro pattern matching and expansion. Tracks captured values, active repetition scopes, and repetition ownership per placeholder.

Fields

captures: OrderedHashMap<SmolStrId<'db>, Vec<CapturedValue<'db>>>

The captured values per macro parameter name. These are flat lists, even for repeated placeholders.

placeholder_to_rep_id: OrderedHashMap<SmolStrId<'db>, RepetitionId>

Maps each placeholder to the RepetitionId of the repetition block they are part of. This helps the expansion phase know which iterators to advance together.

current_repetition_stack: Vec<RepetitionId>

Stack of currently active repetition blocks. Used to assign placeholders to their correct RepetitionId while recursing into nested repetitions.

next_repetition_id: usize

Counter for generating unique RepetitionIds.

repetition_indices: OrderedHashMap<RepetitionId, usize>

Tracks the current index for each active repetition during expansion.

repetition_match_counts: OrderedHashMap<RepetitionId, usize>

Count how many times each repetition matched.

repetition_operators: OrderedHashMap<RepetitionId, MacroRepetitionOperator<'db>>

Store the repetition operator for each repetition.

Trait Implementations
