Struct LexState 

pub struct LexState {
    pub current: i32,
    pub linenumber: i32,
    pub lastline: i32,
    pub t: LexToken,
    pub lookahead: LexToken,
    pub fs: Option<Box<FuncState>>,
    pub dyd: DynData,
    pub source: Option<GcRef<LuaString>>,
    pub envn: Option<GcRef<LuaString>>,
    pub lex: LexState,
    pub recursion_depth: u32,
}

C: LexState — per-chunk lexer + parser state. PORT NOTE: This is a Phase A stub. In Phase B, LexState lives in lua-lex and lua-parse imports it. FuncState will move here or be passed separately. The fs field creates a circular-crate dependency that Phase B must resolve (likely: both live in one crate).

Fields

current: i32

C: current — current character (i32; -1 = EOZ)

linenumber: i32

C: linenumber

lastline: i32

C: lastline

t: LexToken

C: t — current token

lookahead: LexToken

C: lookahead — one-token lookahead

fs: Option<Box<FuncState>>

C: fs — current FuncState (parser owns this)

dyd: DynData

C: dyd — parser dynamic data

source: Option<GcRef<LuaString>>

C: source — chunk name

envn: Option<GcRef<LuaString>>

C: envn — cached “_ENV” string

lex: LexState

Underlying lexer state that owns the ZIO stream and lex buffer. The parser drives the lexer by calling lex_next / lex_lookahead, which forward to lua_lex::next / lua_lex::lookahead on this inner state and then mirror the resulting token into self.t / self.lookahead.

recursion_depth: u32

Parser recursion depth for C-Lua’s enterlevel / leavelevel guard.
