What's the recommended way to create custom containers, which can hold indirect self-references? From my testing, they never get garbage-collected.
Example Lua code
do
local container = myApi.makeContainer()
container:insert({
callback = function()
container:insert({}) -- capture container in a closure
end
})
end
collectGarbage()
-- container doesn't get garbage-collected because of the cyclic reference
The cases I tested were basically various std::vector / std::map wrappers, or even just a struct with a sol::table field, passed to Lua as userdata with usertypes.
Is such a pattern not supported at all, and all such containers should be implemented on the Lua side?
