Detailed Description

Tracks state allocations.

Allocations are tracked for each of the types described in the lua_Alloc documentation (parameter osize), corresponding to the elements of the static array types. Each position in the array v contains the allocation information for the corresponding type in types. One extra position at the end (i.e. at position types.size()) holds information for "other" types.

lua_alloc is a static function which can serve as lua_Alloc allocator. Its d parameter should be the address of an object of this type. malloc(3), realloc(3), and free(3) will be used for actual memory allocations.

◆ lua_alloc() [1/2]

void * nngn::lua::alloc_info::lua_alloc	(	void *	d,
		void *	p,
		std::size_t	s0,
		std::size_t	s1
	)

static

Function to be passed to lua_newstate.

Here is the caller graph for this function:

◆ lua_alloc() [2/2]

static void * nngn::lua::alloc_info::lua_alloc	(	void *	d,
		void *	p,
		std::size_t	s0,
		std::size_t	s1
	)

static

Function to be passed to lua_newstate.

Member Data Documentation

◆ n_types

static constexpr auto nngn::lua::alloc_info::n_types = 1 + std::tuple_size_v<>

staticconstexpr

Number of types for which allocations are tracked.

One extra position for "other".

◆ types

static constexpr std::array nngn::lua::alloc_info::types

staticconstexpr

Initial value:

= {
        type::string, type::table, type::function, type::user_data,
        type::thread,
    }

Each entry corresponds to the allocation information in v.

◆ v

std::array< info, n_types > nngn::lua::alloc_info::v = {}

Total size in bytes of active allocations for each type.

Types are in the same order as types.
