* @dev Library for managing
* https://en.wikipedia.org/wiki/Set_(abstract_data_type)[sets] of primitive
* types.
*
* Sets have the following properties:
*
* - Elements are added, removed, and checked for existence in constant time
* (O(1)).
* - Elements are enumerated in O(n). No guarantees are made on the ordering.
* - Set can be cleared (all elements removed) in O(n).
*
* ```solidity
* contract Example {
* // Add the library methods
* using EnumerableSet for EnumerableSet.AddressSet;
*
* // Declare a set state variable
* EnumerableSet.AddressSet private mySet;
* }
* ```
*
* The following types are supported:
*
* - `bytes32` (`Bytes32Set`) since v3.3.0
* - `address` (`AddressSet`) since v3.3.0
* - `uint256` (`UintSet`) since v3.3.0
* - `string` (`StringSet`) since v5.4.0
* - `bytes` (`BytesSet`) since v5.4.0
*
* [WARNING]
* ====
* Trying to delete such a structure from storage will likely result in data corruption, rendering the structure
* unusable.
* See https://github.com/ethereum/solidity/pull/11843[ethereum/solidity#11843] for more info.
*
* In order to clean an EnumerableSet, you can either remove all elements one by one or create a fresh instance using an
* array of EnumerableSet.
