Types

type Element added in v0.2.12 

type Element generic.Type

type ElementCapsule added in v0.2.12 

type ElementCapsule struct {
	// contains filtered or unexported fields
}

ElementCapsule is something like an optional type, it holds boolean about whether it contains value though it does not hold pointer

type ElementStorage added in v0.2.12 

type ElementStorage struct {
	// contains filtered or unexported fields
}

ElementStorage generates IDs witch makes no need to use hashing, only drawback is that you cannot choose the id, it will be assigned like a pointer, but without putting presure no gc, brilliant ElementStorage for components. Its highly unlikely you will run out of ids as they are reused

func (*ElementStorage) Allocate added in v0.2.12 

func (s *ElementStorage) Allocate() (*Element, int32)

Allocate allocates an value and returns id and pointer to it. Note that allocate does not always allocate at all and just reuses freed space, returned pointer also does not point to zero value and you have to overwrite all properties to get expected behavior

func (*ElementStorage) AllocateID added in v0.2.12 

func (s *ElementStorage) AllocateID(id int32) *Element
