Functions ¶
func OnceValues ¶
func OnceValues[T1, T2 any](f func() (T1, T2)) func() (T1, T2)
Types ¶
type Map ¶
type Map[K comparable, V any] struct { // contains filtered or unexported fields }
Map is a thread-safe generic map implementation on top of sync.Map
func NewMap ¶
func NewMap[K comparable, V any]() *Map[K, V]
func (*Map[K, V]) LoadOrStore ¶
func (*Map[K, V]) LoadOrStoreFunc ¶
func (m *Map[K, V]) LoadOrStoreFunc(key K, generator func(key K) (value V)) (value V)
LoadOrStoreFunc loads the value for the given key, if it exists. If the key does not exist, it calls the generator function to create the value and stores it in the map. The generator function is guaranteed to be called synchronously and only once for the same key.
