Modules

• analysis
  Module with functionalities for grammar analysis
• build
  Allows programmatically invoking parol from a build.rs script
• conversions
  Module with functionalities for grammar conversion
• generators
  Module with functionalities for lexer and parser generation
• grammar
  Basic grammar data structures and algorithms
• parser
  Module with parol’s parser for input grammars

Structs

• ParolErrorReporter
  Error reporter for user errors generated by the parol parser itself.

Constants

• MAX_K
  Constant lookahead limit, which is used for the calculation of the lookahead sets. The value is used to limit the number of iterations in the calculation of the lookahead sets. Grammar with a higher value will be rejected.

Traits

• CommonGeneratorConfig
  Common configuration of both parser generator an user trait generator.
• ParserGeneratorConfig
  Configuration of parser generator
• UserTraitGeneratorConfig
  Configuration of user trait generator
