+# Rust Skeleton Audio Control HAL implementation.
+
+WARNING: This is not a reference audio control HAl implementation and does
+not contain any actual implementation.
+
+This folder contains a skeleton audio control HAL implementation in Rust to
+demonstrate  how vendor may implement a Rust audio control HAL. To run this
+audio control HAL, include
+`android.hardware.automotive.audiocontrol-V4-rust-service` in your image.
+
+This implementation returns `StatusCode::UNKNOWN_ERROR` for all operations
+and does not pass VTS/CTS. Vendor must replace the logic in
+`default_audio_control_hal.rs` with the actual implementation.

The maxFloatValue indicates the maximum temperature setting in Celsius.\nIf all the values between minFloatValue and maxFloatValue are not supported, the configArray can be used to list the valid temperature values that can be set. It also describes a lookup table to convert the temperature from Celsius to Fahrenheit and vice versa for this vehicle. The configArray must be defined if standard unit conversion is not supported on this vehicle.\nThe configArray is set as follows: configArray[0] = [the lower bound of the supported temperature in Celsius] * 10. configArray[1] = [the upper bound of the supported temperature in Celsius] * 10. configArray[2] = [the increment in Celsius] * 10. configArray[3] = [the lower bound of the supported temperature in Fahrenheit] * 10. configArray[4] = [the upper bound of the supported temperature in Fahrenheit] * 10. configArray[5] = [the increment in Fahrenheit] * 10.\nThe minFloatValue and maxFloatValue in VehicleAreaConfig must be equal to configArray[0] and configArray[1] respectively.\nFor example, if the vehicle supports temperature values as: [16.0, 16.5, 17.0 ,..., 28.0] in Celsius [60.5, 61.5, 62.5 ,..., 84.5] in Fahrenheit The configArray should be configArray = {160, 280, 5, 605, 845, 10}.\nIdeally, the ratio of the Celsius increment to the Fahrenheit increment should be as close to the actual ratio of 1 degree Celsius to 1.8 degrees Fahrenheit.\nThere must be a one to one mapping of all Celsius values to Fahrenheit values defined by the configArray. The configArray will be used by clients to convert this property's temperature from Celsius to Fahrenheit. Also, it will let clients know what Celsius value to set the property to achieve their desired Fahreneheit value for the system. If the ECU does not have a one to one mapping of all Celsius values to Fahrenheit values, then the config array should only define the list of Celsius and Fahrenheit values that do have a one to one mapping.\nFor example, if the ECU supports Celsius values from 16 to 28 and Fahrenheit values from 60 to 85 both with an increment of 1, then one possible configArray would be {160, 280, 10, 600, 840, 20}. In this case, 85 would not be a supported temperature.\nAny value set in between a valid value should be rounded to the closest valid value.\nIt is highly recommended that the OEM also implement the HVAC_TEMPERATURE_VALUE_SUGGESTION vehicle property because it provides applications a simple method for determining temperature values that can be set for this vehicle and for converting values between Celsius and Fahrenheit.\nThis property is defined as VehiclePropertyAccess.READ_WRITE, but OEMs have the option to implement it as VehiclePropertyAccess.READ only."

It is recommended for the OEM to add custom logic in their VHAL implementation in order to avoid making requests to the HVAC ECU.\nThe logic can be as follows: For converting the temperature from celsius to fahrenheit use the following: \/\/ Given tempC and the configArray float minTempC = configArray[0] \/ 10.0; float temperatureIncrementCelsius = configArray[2] \/ 10.0; float minTempF = configArray[3] \/ 10.0; float temperatureIncrementFahrenheit = configArray[5] \/ 10.0; \/\/ Round to the closest increment int numIncrements = round((tempC - minTempC) \/ temperatureIncrementCelsius); tempF = temperatureIncrementFahrenheit * numIncrements + minTempF;\nFor example, when a user uses the voice assistant to set HVAC temperature to 66.2 in Fahrenheit. First, an application will set this property with the value [66.2, (float)VehicleUnit.FAHRENHEIT,0,0]. If OEMs suggest to set 19.0 in Celsius or 66.5 in Fahrenheit for user's request, then VHAL must generate a callback with property value [66.2, (float)VehicleUnit.FAHRENHEIT, 19.0, 66.5]. After the voice assistant gets the callback, it will inform the user and set HVAC temperature to the suggested value.\nAnother example, an application receives 21 Celsius as the current temperature value by querying HVC_TEMPERATURE_SET. But the application wants to know what value is displayed on the car's UI in Fahrenheit. For this, the application sets the property to [21, (float)VehicleUnit.CELSIUS, 0, 0]. If the suggested value by the OEM for 21 Celsius is 70 Fahrenheit, then VHAL must generate a callback with property value [21, (float)VehicleUnit.CELSIUS, 21.0, 70.0]. In this case, the application can know that the value is 70.0 Fahrenheit in the car’s UI."

For example, user A unlocked the car using the key fob of user B; the INITIAL_USER_INFO request returned user B, but then a face recognition subsubsystem identified the user as A.\nThe HAL makes this request by a property change event (passing a negative request id), and the Android system will response by issue an ANDROID_POST_SWITCH call which the same request id.\nFor example, if the current foreground Android user is 10 and the HAL asked it to switch to 11, the request would be:\nint32[0]: -108  \/\/ request id int32[1]: 4     \/\/ messageType = SwitchUserMessageType::VEHICLE_REQUEST int32[2]: 11    \/\/ Android user id\nIf the request succeeded and Android has 3 users (0, 10, 11), the response would be:\nint32[0]: -108 \/\/ request id int32[1]:  5   \/\/ messageType = SwitchUserMessageType::ANDROID_POST_SWITCH int32[2]:  11  \/\/ target user id int32[3]:  0   \/\/ target user id flags (none) int32[4]:  11  \/\/ current user int32[5]:  0   \/\/ current user flags (none) int32[6]:  3   \/\/ number of users int32[7]:  0   \/\/ 1st user (user 0) int32[8]:  0   \/\/ 1st user flags (none) int32[9]:  10  \/\/ 2nd user (user 10) int32[10]: 4   \/\/ 2nd user flags (none) int32[11]: 11  \/\/ 3rd user (user 11) int32[12]: 3   \/\/ 3rd user flags (none)\nNotice that both the current and target user ids are the same - if the request failed, then they would be different (i.e, target user would be 11, but current user would still be 10).\n5.ANDROID_POST_SWITCH --------------------- Called by the Android System after a request to switch a user was made.\nThis property is called after switch requests of any type (i.e., LEGACY_ANDROID_SWITCH, ANDROID_SWITCH, or VEHICLE_REQUEST) and can be used to determine if the request succeeded or failed:\n1. When it succeeded, it's called when the Android user is in the unlocked state and the value of the current and target users ids in the response are the same. This would be equivalent to receiving an Intent.ACTION_USER_UNLOCKED in an Android app. 2. When it failed it's called right away and the value of the current and target users ids in the response are different (as the current user didn't change to the target). 3. If a new switch request is made before the HAL responded to the previous one or before the user was unlocked, then the ANDROID_POST_SWITCH request is not made. For example, the driver could accidentally switch to the wrong user which has lock credentials, then switch to the right one before entering the credentials.\nThe HAL can update its internal state once it receives this request, but it doesn't need to reply back to the Android System.\nRequest: the first N values as defined by INITIAL_USER_INFO (where the request-specific value at index 1 is SwitchUserMessageType::ANDROID_POST_SWITCH), then 2 more values for the target user id (i.e., the Android user id that was requested to be switched to) and its flags (as defined by  UserFlags).\nResponse: none.\nExample: see VEHICLE_REQUEST section above."

In fact, this property could be used without supporting the core user-related functions described on INITIAL_USER_INFO.\nTo query the association, the Android system gets the property, passing a VehiclePropValue containing the types of associations are being queried, as defined by UserIdentificationGetRequest. The HAL must return right away, returning a VehiclePropValue with a UserIdentificationResponse. Notice that user identification should have already happened while system is booting up and the VHAL implementation should only return the already identified association (like the key FOB used to unlock the car), instead of starting a new association from the get call.\nTo associate types, the Android system sets the property, passing a VehiclePropValue containing the types and values of associations being set, as defined by the UserIdentificationSetRequest. The HAL will then use a property change event (whose VehiclePropValue is defined by UserIdentificationResponse) indicating the current status of the types after the request.\nFor example, to query if the current user (10) is associated with the FOB that unlocked the car and a custom mechanism provided by the OEM, the request would be:\nint32[0]: 42  \/\/ request id int32[1]: 10  (Android user id) int32[2]: 0   (Android user flags) int32[3]: 2   (number of types queried) int32[4]: 1   (1st type queried, UserIdentificationAssociationType::KEY_FOB) int32[5]: 101 (2nd type queried, UserIdentificationAssociationType::CUSTOM_1)\nIf the user is associated with the FOB but not with the custom mechanism, the response would be:\nint32[0]: 42  \/\/ request id int32[1]: 2   (number of associations in the response) int32[2]: 1   (1st type: UserIdentificationAssociationType::KEY_FOB) int32[3]: 2   (1st value: UserIdentificationAssociationValue::ASSOCIATED_CURRENT_USER) int32[4]: 101 (2st type: UserIdentificationAssociationType::CUSTOM_1) int32[5]: 4   (2nd value: UserIdentificationAssociationValue::NOT_ASSOCIATED_ANY_USER)\nThen to associate the user with the custom mechanism, a set request would be made:\nint32[0]: 43  \/\/ request id int32[1]: 10  (Android user id) int32[2]: 0   (Android user flags) int32[3]: 1   (number of associations being set) int32[4]: 101 (1st type: UserIdentificationAssociationType::CUSTOM_1) int32[5]: 1   (1st value: UserIdentificationAssociationSetValue::ASSOCIATE_CURRENT_USER)\nIf the request succeeded, the response would be simply:\nint32[0]: 43  \/\/ request id int32[1]: 1   (number of associations in the response) int32[2]: 101 (1st type: UserIdentificationAssociationType::CUSTOM_1) int32[3]: 1   (1st value: UserIdentificationAssociationValue::ASSOCIATED_CURRENT_USER)\nNotice that the set request adds associations, but doesn't remove the existing ones.

+# Rust Skeleton BroadcastRadio HAL implementation.
+
+WARNING: This is not a reference BroadcastRadio HAL implementation and does
+not contain any actual implementation.
+
+This folder contains a skeleton broadcast radio HAL implementation in Rust to
+demonstrate  how vendor may implement a Rust broadcast radio HAL. To run this
+broadcast radio HAL, include `android.hardware.broadcastradio-rust-service`
+in your image.
+
+This implementation returns `StatusCode::UNKNOWN_ERROR` for all operations
+and does not pass VTS/CTS. Vendor must replace the logic in
+`default_broadcastradio_hal.rs` with the actual implementation
