Once is a wrapper around an initialization function, ensuring it happens only once, even in a concurrent environment.

func New

New creates a new Once wrapper around an initialization function.

func (*Once[T]) Get

func (s *Once[T]) Get() T

Get returns the initialized object, creating it if necessary.
