Equatable without the need to implement == func

BinaryEquatable.swift

protocol BinaryEquatable: Equatable { }

extension BinaryEquatable {
    static func == (lhs: Self, rhs: Self) -> Bool {
        withUnsafeBytes(of: lhs) { lhsBytes -> Bool in
            withUnsafeBytes(of: rhs) { rhsBytes -> Bool in
                lhsBytes.elementsEqual(rhsBytes)
            }
        }
    }
}

// Example:

enum TestEnum {
    case option1
    case option2(String)
    case option3(String, completion: (() -> Void)?)
}

extension TestEnum: BinaryEquatable { }

TestEnum.option1 == TestEnum.option1 // true
TestEnum.option1 == TestEnum.option2("abc") // false
TestEnum.option2("abc") == TestEnum.option2("abc") // true
TestEnum.option2("abc") == TestEnum.option2("xyz") // false
TestEnum.option2("abc") == TestEnum.option3("abc", completion: { }) // false
TestEnum.option3("abc", completion: nil) == TestEnum.option3("abc", completion: nil) // true
TestEnum.option3("abc", completion: { }) == TestEnum.option3("abc", completion: nil) // false
