Structs

ASTModificationError

Any error from the Yacc parser returns an instance of this struct.

ASTWithValidityInfo

Contains a GrammarAST structure produced from a grammar source file. As well as any errors which occurred during the construction of the AST.

GrammarAST

An AST representing a grammar. This is built up gradually: when it is finished, the complete_and_validate must be called exactly once in order to finish the set-up. At that point, any further mutations made to the struct lead to undefined behaviour.
