| /// The `=!=` operator assigns the value on the right-hand side to the variable on the left-hand side | |
| /// only if the two values are not equal. This operator is designed for types conforming to the `Equatable` protocol. | |
| /// | |
| /// - Parameters: | |
| /// - lhs: The variable to be assigned a new value if not equal. | |
| /// - rhs: The value to be assigned to the variable if it is not equal to the current value. | |
| /// | |
| /// - Precondition: The type of the operands must conform to the `Equatable` protocol. | |
| /// | |
| /// - Precedence: `AssignIfNotEqualPrecedence` | |
| /// | |
| /// - Complexity: O(1) | |
| /// | |
| /// - Note: The assignment operation is performed only if `lhs != rhs`. | |
| /// | |
| /// - Example: | |
| /// ```swift | |
| /// var x = 42 | |
| /// let y = 24 | |
| /// x =!= y // x is now 24 | |
| /// ``` | |
