LexerAtn

Struct LexerAtn 

Source
pub struct LexerAtn { /* private fields */ }
Expand description

Deserialized lexer Abstract Transition Network.

The structure keeps the state graph plus ANTLR side tables such as rule-to-start, rule-to-token, mode-to-start, decisions, and actions. Parser ATNs never use this object-graph representation.
