Types

type AsyncMap

type AsyncMap[K comparable, V any] struct {
	// contains filtered or unexported fields
}

AsyncMap is a generic implementation of a safe map. K is the key and V is the value.

Supports multiple concurrent reads and writes with the sync.RWMutex

func NewAsyncMap

func NewAsyncMap[K comparable, V any]() *AsyncMap[K, V]

Instantiates a new AsyncMap.

func (*AsyncMap[K, V]) Clear

func (s *AsyncMap[K, V]) Clear()

deletes all elements in the map

func (*AsyncMap[K, V]) Contains

func (s *AsyncMap[K, V]) Contains(key K) bool

Returns true if key in map

func (*AsyncMap[K, V]) Delete

func (s *AsyncMap[K, V]) Delete(key K)

deletes the element with the specified key

func (*AsyncMap[K, V]) Get

func (s *AsyncMap[K, V]) Get(key K) (V, bool)

Returns V and true if key in map.

func (*AsyncMap[K, V]) IsEmpty

func (s *AsyncMap[K, V]) IsEmpty() bool

Returns true is map has zero elements

func (*AsyncMap[K, V]) Keys

func (s *AsyncMap[K, V]) Keys() []K

Returns a slice of the keys in the map

func (*AsyncMap[K, V]) Len

func (s *AsyncMap[K, V]) Len() int

deletes all elements in the map

func (*AsyncMap[K, V]) Set

func (s *AsyncMap[K, V]) Set(key K, value V)

Inserts V in map under the key

func (*AsyncMap[K, V]) Values

func (s *AsyncMap[K, V]) Values() []V

Returns a slice of all the values in the map This function copies the underlying data, so it is safe to use after the map has been modified.
