lazyget

Overview ¶

Package lazyget provides a simple way to create thread-safe, type-safe getter functions to lazily initialize, cache, and return a value of a given type. It uses a sync.Once to ensure that the initialization function is only called once, even in concurrent environments. All subsequent calls will return the cached value.

Usage:

var GetResource = lazyget.New(func() *Resource {
	// do some expensive initialization here
	return &Resource{}
})

r := GetResource() // r is of type *Resource
