TokenValue

Enum TokenValue 

Source
pub enum TokenValue {
    None,
    Float(f64),
    Int(i64),
    Str(GcRef<LuaString>),
}
Expand description

Semantic payload carried by a token.

Corresponds to SemInfo (a C union) in llex.h. In Rust this is a discriminated union (enum).

§C mapping

SemInfo.r   → TokenValue::Float(f64)      (lua_Number)
SemInfo.i   → TokenValue::Int(i64)        (lua_Integer)
SemInfo.ts  → TokenValue::Str(GcRef<LuaString>)
(no C field) → TokenValue::None           (default / unset)

Variants§

§

None

No semantic value (default; used for single-byte and most multi-char tokens).

§

Float(f64)

Float literal payload. C: seminfo.r (lua_Number).

§

Int(i64)

Integer literal payload. C: seminfo.i (lua_Integer).

§

Str(GcRef<LuaString>)

String/name payload. C: seminfo.ts (TString *).
