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]) CompareAndSwap ¶

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

CompareAndSwap swaps the old and new values for key if the value stored in the map is equal to old. The old value must be of a comparable type.

func (*SyncMap[K, V]) Delete ¶

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

Delete deletes the value for a key.

func (*SyncMap[K, V]) Load ¶

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

Load returns the value stored in the map for a key, or nil 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)

LoadAndDelete deletes the value for a key, returning the previous value if any. The loaded result reports whether the key was present.

func (*SyncMap[K, V]) LoadOrStore ¶

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

LoadOrStore returns the existing value for the key if present. Otherwise, it stores and returns the given value. The loaded result is true if the value was loaded, false if stored.

func (*SyncMap[K, V]) Range ¶

func (m *SyncMap[K, V]) Range() iter.Seq2[K, V]

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, old V) (deleted bool)

CompareAndDelete deletes the entry for key if its value is equal to old. The old value must be of a comparable type.

If there is no current value for key in the map, CompareAndDelete returns false (even if the old value is the nil interface value).
