pub unsafe extern "C-unwind" fn lua_gettable(
    l: *mut lua_State,
    index: c_int,
)
Expand description

Pushes onto the stack the value t[k], where t is the value at the given valid index and k is the value at the top of the stack. [-1, +1, e]

This function pops the key from the stack (putting the resulting value in its place). As in Lua, this function may trigger a metamethod for the “index” event
