Variable documentation

flat_hash_map<const syntax::SyntaxNode*, Node> slang::parsing::ParserMetadata::nodeMap

Specific metadata that was in effect when certain syntax nodes were parsed (such as various bits of preprocessor state).

flat_hash_set<std::string_view> slang::parsing::ParserMetadata::globalInstances

A set of names of all instantiations of global modules/interfaces/programs. This can be used to determine which modules should be considered as top-level roots of the design.

std::vector<const syntax::IdentifierNameSyntax*> slang::parsing::ParserMetadata::classPackageNames

A list of all names parsed that could represent a package or class name, since they are simple names that appear on the left-hand side of a double colon.

Token slang::parsing::ParserMetadata::eofToken

The EOF token, if one has already been consumed by the parser. Otherwise an empty token.
