pub fn open_debug(state: &mut LuaState) -> Result<usize, LuaError>Expand description
Open the debug library and push the module table onto the stack.
Returns 1 (the table).
The roster is version-gated: setcstacklimit is a 5.4-only addition
(removed again in 5.5), and the 5.1 backend swaps the modern upvalue/
uservalue accessors for the fenv accessors getfenv/setfenv. Every delta
is verified against that version’s reference binary.
