pub fn gmatch_aux(state: &mut LuaState) -> Result<usize, LuaError>Expand description
Continuation function for string.gmatch iterator closure.
PORT NOTE: C stores source, pattern, and GMatchState as three C-closure
upvalues. The Rust port mirrors that shape: upvalues 1 and 2 are traced Lua
strings, and upvalue 3 is a full userdata whose host payload stores only the
mutable byte positions.
