Enum Value 

pub enum Value {
    None,
    Term(Term),
    Index(usize),
}

Represents a generic value emitted by the lexer.

Value encapsulates auxiliary data produced during lexing, such as parsed terms or indices into the parser’s term stack.

Variants

• Value::None — Indicates absence of a value.
• Value::Term — Wraps a parsed Term instance.
• Value::Index — Holds a numeric index to terms stack TermsParserDriver::terms.

Variants
