Method Range

pkg/concurrent/map.go:93–103

Range calls f for every key/value pair in the map. Iteration stops early if f returns false. Range iterates over a snapshot of the map taken under a read lock; f is invoked without holding any lock, which means callbacks may safely call other methods on the same Map (including Store and Delete) wit

(f func(key K, value V) bool)

// deadlocking. As a consequence, mutations performed during iteration are not
// reflected in the values seen by f.
func (m *Map[K, V]) Range(f func(key K, value V) bool) {
	m.mu.RLock()
	snapshot := maps.Clone(m.values)
	m.mu.RUnlock()

	for k, v := range snapshot {
		if !f(k, v) {
			break
		}
	}
}
