store

func (*KV[K, V]) Clear ¶

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

Clear removes all keys and resets the inner map.

func (*KV[K, V]) Delete ¶

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

Delete removes a key-value pair from the store.

func (*KV[K, V]) DeleteIf ¶

func (s *KV[K, V]) DeleteIf(key K, expected V) bool

DeleteIf removes key only when the stored value equals expected (same lock). Returns true if the key was deleted.

V must be comparable at runtime (e.g. pointers, strings, ints). Comparing non-comparable values (slices, maps, funcs) panics — same as Go interface ==.

func (*KV[K, V]) Get ¶

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

Get retrieves a value by key.

func (*KV[K, V]) Keys ¶

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

Keys returns all keys in the store.

func (*KV[K, V]) Len ¶

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

Len returns the current count of items stored.

func (*KV[K, V]) Pop ¶

func (s *KV[K, V]) Pop(key K) (V, bool)

Pop atomically retrieves and deletes a key-value pair in a single lock step.

func (*KV[K, V]) Set ¶

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

Set adds or updates a key-value pair.
