Types

type Lazy

type Lazy[T any] interface {
	// Get returns the value, evaluate it if necessary.
	Get() T
	// Evaluated returns whether the value has been evaluated or not.
	Evaluated() bool
}

Lazy defers the evaluation of getter until it's accessed the first access.

func New

func New[T any](getter func() T) Lazy[T]

New returns a new lazily evaluated value. The getter is executed only when it's accessed the first access.
