syncmap

func (*SyncMap[K, V]) Clear ¶

func (m *SyncMap[K, V]) Clear()

Clear deletes all the entries, resulting in an empty Map.

func (*SyncMap[K, V]) CompareAndDelete ¶

func (m *SyncMap[K, V]) CompareAndDelete(key K, old V) bool

CompareAndDelete deletes the entry for key if its value is equal to old.

If there is no current value for key in the map, CompareAndDelete returns false .

func (*SyncMap[K, V]) CompareAndSwap ¶

func (m *SyncMap[K, V]) CompareAndSwap(key K, old V, new V) (swapped bool)

CompareAndSwap swaps the old and new values for key if the value stored in the map is equal to old.

func (*SyncMap[K, V]) Delete ¶

func (m *SyncMap[K, V]) Delete(key K)

Delete deletes the value for a key.

func (*SyncMap[K, V]) Keys ¶

func (m *SyncMap[K, V]) Keys() []K

Keys returns all the keys in the map.

func (*SyncMap[K, V]) Load ¶

func (m *SyncMap[K, V]) Load(key K) (V, bool)

Load returns the value stored in the map for a key, or a zero value if no value is present. The ok result indicates whether value was found in the map.

func (*SyncMap[K, V]) LoadAndDelete ¶

func (m *SyncMap[K, V]) LoadAndDelete(key K) (value V, loaded bool)

func (*SyncMap[K, V]) LoadOrStore ¶

func (m *SyncMap[K, V]) LoadOrStore(key K, value V) (V, bool)

func (*SyncMap[K, V]) Range ¶

func (m *SyncMap[K, V]) Range(f func(key K, value V) bool)

Range calls f sequentially for each key and value present in the map. If f returns false, range stops the iteration.

Range does not necessarily correspond to any consistent snapshot of the Map's contents: no key will be visited more than once, but if the value for any key is stored or deleted concurrently (including by f), Range may reflect any mapping for that key from any point during the Range call. Range does not block other methods on the receiver; even f itself may call any method on m.

Range may be O(N) with the number of elements in the map even if f returns false after a constant number of calls.

func (*SyncMap[K, V]) Store ¶

func (m *SyncMap[K, V]) Store(key K, value V)

Store sets the value for a key.

func (*SyncMap[K, V]) Swap ¶

func (m *SyncMap[K, V]) Swap(key K, value V) (previous V, loaded bool)

Swap swaps the value for a key and returns the previous value if any. The loaded result reports whether the key was present.

func (*SyncMap[K, V]) Values ¶ added in v0.24.6

func (m *SyncMap[K, V]) Values() []V
