# 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-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.
