Module parser 

Structs

BailErrorStrategy

Marker error strategy matching ANTLR’s BailErrorStrategy.

BaseParser

EnterRuleEvent

A rule-entry event delivered to ParseListener::enter_every_rule.

ExpectedTokenSet

Interval-set of expected token types, displayable through a vocabulary — the shape ANTLR’s getExpectedTokens().toString(vocabulary) exposes to generated test actions.

GeneratedDiagnosticsCheckpoint

Rollback marker for speculative generated parser paths.

GeneratedMatch

Outcome of a generated token / set / not-set match that may recover.

NoSemanticHooks

Default hook object used by parsers that do not need user-supplied semantics.

ParserAction

Parser semantic action reached while recognizing one ATN path.

ParserMemberAction

Integer member mutation attached to an ATN action transition.

ParserReturnAction

Integer return-value assignment attached to an ATN action transition.

ParserRuleArg

Integer argument metadata for a generated parser rule invocation.

ParserRuntimeOptions

Optional generated-runtime metadata for metadata-driven parser execution.

ParserSemCtx

Runtime view passed to parser semantic hooks.

ParserSemanticAction

Parser action coordinate lowered into SemIr.

ParserSemanticPredicate

Parser predicate coordinate lowered into SemIr.

ParserSemantics

Data-driven semantic tables emitted by generated parsers.

RecognitionArenaStats

Storage and reachability counters for the most recent interpreted-rule recognition arena.

Enums

ParserPredicate

Parser semantic predicate rendered from a supported target template.

PredictionMode

Prediction strategy requested by generated parser harnesses.

UnknownSemanticPolicy

Policy for semantic predicate coordinates that have no runtime implementation.

Traits

ParseListener

Receives committed rule enter/exit events during recognition, matching ANTLR’s addParseListener contract (Parser::add_parse_listener, also inherent on BaseParser and generated parsers).

Parser

SemanticHooks

User extension point for parser semantic predicates and actions that the metadata generator did not translate into built-in runtime metadata.

Functions

dump_perf_counters

grow_generated_rule_stack

Runs a generated rule body after ensuring native stack capacity, growing onto a segmented stack when remaining capacity enters the red zone.

reset_perf_counters
