smap

Example demonstrates basic usage of the concurrent safe Map including creating, setting, getting, and iterating with All(). The whole point though would be do to these operations concurrently from multiple goroutines.

// Create a new concurrent safe map
m := New[string, int]()

// Add some entries
m.Set("apple", 5)
m.Set("banana", 3)
m.Set("cherry", 8)

// Get a specific value
count, exists := m.Get("banana")
if exists {
	fmt.Printf("Bananas: %d\n", count)
}

// Check the total count
fmt.Printf("Total items: %d\n", m.Len())

// Check if a key exists
fmt.Printf("Has apple: %t\n", m.Has("apple"))

// Iterate over all entries using range
// Note: We collect and sort for deterministic output in this example
var toDelete []string
// Using m.All you can't mutate the map during iteration (use AllSorted or collect changes first, or
// use KeysSnapshot or KeysValuesSnapshot first then mutate)
for fruit, count := range m.All() {
	if count < 8 {
		toDelete = append(toDelete, fruit)
	}
}
m.Delete(toDelete...) // Delete multiple, after iteration
fmt.Printf("After removing items with count < 8, total items: %d\n", m.Len())
fmt.Printf("Map is now just %v\n", m)

Output:
Bananas: 3
Total items: 3
Has apple: true
After removing items with count < 8, total items: 1
Map is now just map[cherry:8]
