This is to prove that rust broadcast radio HAL can be built and can

for all APIs.

# 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
