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

Init represents the structure.

func (l *Init) Do(f func() error) error

Do is similar to sync.Once.Do - makes one successful call to the function. ie, it invokes the function if it is not successful yet.

func (l *Init) DoWithContext(ctx context.Context, f func(context.Context) error) error

DoWithContext is similar to Do except that it accepts a context as an argument to be passed.

type Singleton[T any] struct {
	// contains filtered or unexported fields
}

Singleton contains a pointer to T that must be set once. Until the value is set all Get() calls will block.

func NewSingleton[T any]() *Singleton[T]

NewSingleton creates a new unset singleton.

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

Get will return the singleton value.

func (s *Singleton[T]) GetNonBlocking() *T

GetNonBlocking will return the singleton value or nil if not set yet.

func (s *Singleton[T]) IsSet() bool

IsSet will return whether the singleton has been set.

func (s *Singleton[T]) Set(v *T)

Set the value and unblock all Get requests. This may only be called once, a second call will panic.
