* # HashSet
*
* An immutable `HashSet` provides a collection of unique values with efficient
* lookup, insertion and removal. Once created, a `HashSet` cannot be modified;
* any operation that would alter the set instead returns a new `HashSet` with
* the changes. This immutability offers benefits like predictable state
* management and easier reasoning about your code.
*
* ## What Problem Does It Solve?
*
* `HashSet` solves the problem of maintaining an unsorted collection where each
* value appears exactly once, with fast operations for checking membership and
* adding/removing values.
*
* ## When to Use
*
* Use `HashSet` when you need:
*
* - A collection with no duplicate values
* - Efficient membership testing (**`O(1)`** average complexity)
* - Set operations like union, intersection, and difference
* - An immutable data structure that preserves functional programming patterns
*
* ## Advanced Features
*
* HashSet provides operations for:
*
* - Transforming sets with map and flatMap
* - Filtering elements with filter
* - Combining sets with union, intersection and difference
* - Performance optimizations via mutable operations in controlled contexts
*
* ## Performance Characteristics
*
* - **Lookup** operations ({@link module:HashSet.has}): **`O(1)`** average time
* complexity
* - **Insertion** operations ({@link module:HashSet.add}): **`O(1)`** average time
* complexity
* - **Removal** operations ({@link module:HashSet.remove}): **`O(1)`** average
* time complexity
* - **Set** operations ({@link module:HashSet.union},
* {@link module:HashSet.intersection}): **`O(n)`** where n is the size of the
* smaller set
* - **Iteration**: **`O(n)`** where n is the size of the set
*
* The HashSet data structure implements the following traits:
*
* - {@link Iterable}: allows iterating over the values in the set
* - {@link Equal}: allows comparing two sets for value-based equality
* - {@link Pipeable}: allows chaining operations with the pipe operator
* - {@link Inspectable}: allows inspecting the contents of the set
*

*
* ## Notes
*
* ### Composability with the Effect Ecosystem:
*
* This `HashSet` is designed to work seamlessly within the Effect ecosystem. It
* implements the {@link Iterable}, {@link Equal}, {@link Pipeable}, and
* {@link Inspectable} traits from Effect. This ensures compatibility with other
* Effect data structures and functionalities. For example, you can easily use
* Effect's `pipe` method to chain operations on the `HashSet`.
*
* **Equality of Elements with Effect's {@link Equal `Equal`} Trait:**
*
* This `HashSet` relies on Effect's {@link Equal} trait to determine the
* uniqueness of elements within the set. The way equality is checked depends on
* the type of the elements:
*
* - **Primitive Values:** For primitive JavaScript values like strings, numbers,
* booleans, `null`, and `undefined`, equality is determined by their value
* (similar to the `===` operator).
* - **Objects and Custom Types:** For objects and other custom types, equality is
* determined by whether those types implement the {@link Equal} interface
* themselves. If an element type implements `Equal`, the `HashSet` will
* delegate to that implementation to perform the equality check. This allows
* you to define custom logic for determining when two instances of your
* objects should be considered equal based on their properties, rather than
* just their object identity.
*
* ```ts
* import { Equal, Hash, HashSet } from "effect"
*
* class Person implements Equal.Equal {
* constructor(
* readonly id: number, // Unique identifier
* readonly name: string,
* readonly age: number
* ) {}
*
* // Define equality based on id, name, and age
* [Equal.symbol](that: Equal.Equal): boolean {
* if (that instanceof Person) {
* return (
* Equal.equals(this.id, that.id) &&
* Equal.equals(this.name, that.name) &&
* Equal.equals(this.age, that.age)
* )
* }
* return false
* }
*
* // Generate a hash code based on the unique id
* [Hash.symbol](): number {
* return Hash.hash(this.id)
* }
* }
*
* // Creating a HashSet with objects that implement the Equal interface
* const set = HashSet.empty().pipe(
* HashSet.add(new Person(1, "Alice", 30)),
* HashSet.add(new Person(1, "Alice", 30))
* )
*
* // HashSet recognizes them as equal, so only one element is stored
* console.log(HashSet.size(set))
* // Output: 1
* ```
*
* **Simplifying Equality and Hashing with `Data` and `Schema`:**
*
* Effect's {@link Data} and {@link Schema `Schema.Data`} modules offer powerful
* ways to automatically handle the implementation of both the {@link Equal} and
* {@link Hash} traits for your custom data structures.
*
* - **`Data` Module:** By using constructors like `Data.struct`, `Data.tuple`,
* `Data.array`, or `Data.case` to define your data types, Effect
* automatically generates the necessary implementations for value-based
* equality and consistent hashing. This significantly reduces boilerplate and
* ensures correctness.
*
* ```ts
* import { HashSet, Data, Equal } from "effect"
* import assert from "node:assert/strict"
*
* // Data.* implements the `Equal` traits for us
* const person1 = Data.struct({ id: 1, name: "Alice", age: 30 })
* const person2 = Data.struct({ id: 1, name: "Alice", age: 30 })
*
* assert(Equal.equals(person1, person2))
*
* const set = HashSet.empty().pipe(
* HashSet.add(person1),
* HashSet.add(person2)
* )
*
* // HashSet recognizes them as equal, so only one element is stored
* console.log(HashSet.size(set)) // Output: 1
* ```
*
* - **`Schema` Module:** When defining data schemas using the {@link Schema}
* module, you can use `Schema.Data` to automatically include the `Equal` and
* `Hash` traits in the decoded objects. This is particularly important when
* working with `HashSet`. **For decoded objects to be correctly recognized as
* equal within a `HashSet`, ensure that the schema for those objects is
* defined using `Schema.Data`.**
*
* ```ts
* import { Equal, HashSet, Schema } from "effect"
* import assert from "node:assert/strict"
*
* // Schema.Data implements the `Equal` traits for us
* const PersonSchema = Schema.Data(
* Schema.Struct({
* id: Schema.Number,
* name: Schema.String,
* age: Schema.Number
* })
* )
*
* const Person = Schema.decode(PersonSchema)
*
* const person1 = Person({ id: 1, name: "Alice", age: 30 })
* const person2 = Person({ id: 1, name: "Alice", age: 30 })
*
* assert(Equal.equals(person1, person2)) // Output: true
*
* const set = HashSet.empty().pipe(
* HashSet.add(person1),
* HashSet.add(person2)
* )
*
* // HashSet thanks to Schema.Data implementation of the `Equal` trait, recognizes the two Person as equal, so only one element is stored
* console.log(HashSet.size(set)) // Output: 1
* ```
*
* ### Interoperability with the JavaScript Runtime:
*
* To interoperate with the regular JavaScript runtime, Effect's `HashSet`
* provides methods to access its elements in formats readily usable by
* JavaScript APIs: {@link values `HashSet.values`},
* {@link toValues `HashSet.toValues`}
*
* ```ts
* import { HashSet } from "effect"
*
* const hashSet: HashSet.HashSet<number> = HashSet.make(1, 2, 3)
*
* // Using HashSet.values to convert HashSet.HashSet<A> to IterableIterator<A>
* const iterable: IterableIterator<number> = HashSet.values(hashSet)
*
* console.log(...iterable) // Logs: 1 2 3
*
* // Using HashSet.toValues to convert HashSet.HashSet<A> to Array<A>
* const array: Array<number> = HashSet.toValues(hashSet)
*
* console.log(array) // Logs: [ 1, 2, 3 ]
* ```
*
* Be mindful of performance implications (both time and space complexity) when
* frequently converting between Effect's immutable HashSet and mutable
* JavaScript data structures, especially for large collections.

* membership and adding/removing values, in contexts where mutability is
* preferred for performance or implementation simplicity.
*
* ## When to Use
*
* Use `MutableHashSet` when you need:
*
* - A collection with no duplicate values
* - Efficient membership testing (**`O(1)`** average complexity)
* - In-place modifications for better performance
* - A set that will be built or modified incrementally
* - Local mutability in otherwise immutable code
*
* ## Advanced Features
*
* MutableHashSet provides operations for:
*
* - Adding and removing elements with direct mutation
* - Checking for element existence
* - Clearing all elements at once
* - Converting to/from other collection types
*
* ## Performance Characteristics
*
* - **Lookup** operations ({@link module:MutableHashSet.has}): **`O(1)`** average
* time complexity
* - **Insertion** operations ({@link module:MutableHashSet.add}): **`O(1)`**
* average time complexity
* - **Removal** operations ({@link module:MutableHashSet.remove}): **`O(1)`**
* average time complexity
* - **Iteration**: **`O(n)`** where n is the size of the set
*
* The MutableHashSet data structure implements the following traits:
*
* - {@link Iterable}: allows iterating over the values in the set
* - {@link Pipeable}: allows chaining operations with the pipe operator
* - {@link Inspectable}: allows inspecting the contents of the set
*
* ## Operations Reference
*
* | Category | Operation | Description | Complexity |
* | ------------ | ------------------------------------------ | ----------------------------------- | ---------- |
* | constructors | {@link module:MutableHashSet.empty} | Creates an empty MutableHashSet | O(1) |
* | constructors | {@link module:MutableHashSet.fromIterable} | Creates a set from an iterable | O(n) |
* | constructors | {@link module:MutableHashSet.make} | Creates a set from multiple values | O(n) |
* | | | | |
* | elements | {@link module:MutableHashSet.has} | Checks if a value exists in the set | O(1) avg |
* | elements | {@link module:MutableHashSet.add} | Adds a value to the set | O(1) avg |
* | elements | {@link module:MutableHashSet.remove} | Removes a value from the set | O(1) avg |
* | elements | {@link module:MutableHashSet.size} | Gets the number of elements | O(1) |
* | elements | {@link module:MutableHashSet.clear} | Removes all values from the set | O(1) |
*
* ## Notes
*
* ### Mutability Considerations:
*
* Unlike most data structures in the Effect ecosystem, `MutableHashSet` is
* mutable. This means that operations like `add`, `remove`, and `clear` modify
* the original set rather than creating a new one. This can lead to more
* efficient code in some scenarios, but requires careful handling to avoid
* unexpected side effects.
*
* ### When to Choose `MutableHashSet` vs {@link module:HashSet}:
*
* - Use `MutableHashSet` when you need to build or modify a set incrementally and
* performance is a priority
* - Use `HashSet` when you want immutability guarantees and functional
* programming patterns
* - Consider using {@link module:HashSet}'s bounded mutation context (via
* {@link module:HashSet.beginMutation}, {@link module:HashSet.endMutation}, and
* {@link module:HashSet.mutate} methods) when you need temporary mutability
* within an otherwise immutable context - this approach might be sufficient
* for many use cases without requiring a separate `MutableHashSet`
* - `MutableHashSet` is often useful for local operations where the mutability is
* contained and doesn't leak into the broader application

*
* ## Composition Patterns and Type Safety
*
* When building function pipelines, understanding how types flow through
* operations is critical:
*
* ### Composing with type-preserving operations
*
* Most operations in this module are type-preserving (`number → number`),
* making them easily composable in pipelines:
*
* ```ts
* import { pipe } from "effect"
* import * as Number from "effect/Number"
*
* const result = pipe(
* 10,
* Number.increment, // number → number
* Number.multiply(2), // number → number
* Number.round(1) // number → number
* ) // Result: number (21)
* ```
*
* ### Working with Option results
*
* Operations that might fail (like division by zero) return Option types and
* require Option combinators:
*
* ```ts
* import { pipe, Option } from "effect"
* import * as Number from "effect/Number"
*
* const result = pipe(
* 10,
* Number.divide(0), // number → Option<number>
* Option.getOrElse(() => 0) // Option<number> → number
* ) // Result: number (0)
* ```
*
* ### Composition best practices
*
* - Chain type-preserving operations for maximum composability
* - Use Option combinators when working with potentially failing operations
* - Consider using Effect for operations that might fail with specific errors
* - Remember that all operations maintain JavaScript's floating-point precision
* limitations

* This module provides an implementation of the `Order` type class which is used to define a total ordering on some type `A`.
