<V>(self: MutableHashSet<V>): MutableHashSet<V>Removes all values from the MutableHashSet, mutating the set in place. The set becomes empty after this operation.
When to use
Use to empty a mutable set while keeping the same set instance.
Example (Clearing all values)
import { MutableHashSet } from "effect"
const set = MutableHashSet.make("apple", "banana", "cherry")
console.log(MutableHashSet.size(set)) // 3
// Clear all values
MutableHashSet.clear(set)
console.log(MutableHashSet.size(set)) // 0
console.log(MutableHashSet.has(set, "apple")) // false
console.log(Array.from(set)) // []
// Can still add new values after clearing
MutableHashSet.add(set, "new")
console.log(MutableHashSet.size(set)) // 1export const const clear: <V>(

interface MutableHashSet<out V>A mutable hash set for storing unique values with Effect structural equality
support.
When to use
Use to store and mutate a collection of unique values with Effect hashing and
equality semantics.
Details
Operations mutate the set in place. Values that implement Equal / Hash
can be de-duplicated structurally; other values use normal JavaScript
reference or primitive equality.
Example (Using a mutable hash set)
import { MutableHashSet } from "effect"
// Create a mutable hash set
const set: MutableHashSet.MutableHashSet<string> = MutableHashSet.make(
"apple",
"banana"
)
// Add elements
MutableHashSet.add(set, "cherry")
// Check if elements exist
console.log(MutableHashSet.has(set, "apple")) // true
console.log(MutableHashSet.has(set, "grape")) // false
// Iterate over elements
for (const value of set) {
console.log(value) // "apple", "banana", "cherry"
}
// Get size
console.log(MutableHashSet.size(set)) // 3
