[−][src]Module macro_railroad::lowering

Intermediate representation of a MacroRules and it's transformations.

The representation in this module is more coarse than what the parser provides, yet has still more information than a diagram-node.

Structs

InternalMacroRemover	Replaces macro-variants which start with certain literals with a `macro-internal`-comment.
MacroRules	A more coarse representation of `parser::MacroRules`.

Normalizer	Simplifies a Matcher-tree
SearchVisitor	Tests if any `Matcher` matches a given predicate.
Ungrouper	Unpacks all Groups in a Matcher

A more coarse superset of parser::Matcher.

InspectVisitor	A Visitor to walk `Matcher`.
