/**
 * Result of an operation that can either succeed or fail.
 *
 * `IResult` is an union type that represents the result of an operation
 * that can either succeed or fail.
 *
 * You can distinguished the result by checking the {@link IResult.success} value,
 * and if it's `true`, the success value is stored in {@link IResult.value}.
 * Otherwise, if it's `false`, the error value is stored in {@link IResult.error}.
 *
 * @template T Type of the success value.
 * @template E Type of the error value.
