        RequestHandler.singleCollect {
            val message = it.message ?: context.getString(R.string.error_something_wrong)
            // show toast
            Toast.makeText(context, message, Toast.LENGTH_LONG).show()
            // logcat
            Timber.e(it)
        }

/**

 */
fun UserResponse.toModel(): UserModel {
    return UserModel(
        id = id.toString(),
        login = login ?: "",
    )
