Module recursive 

Informs us about recursive rules.

Structs

Recursion

Calculation of parts of grammar that participate in recursion, be it left-recursion, right-recursion or middle-recursion.

RecursionKind

Informs us about the kind of recursion in a rule.

RecursiveRule

Refers to a grammar rule alongside information about rule recursion and optionally minimal distance to the closest recursion symbol.

RecursiveRules

Iterator over recursive rules with information about the kind of their recursion.

RecursiveRulesWithDistances

Iterator over recursive rules with information about the kind of their recursion as well as symmetric distance to the closest recursion.
