I have an embedded application written in Rust (so using #![no_std]). I am using the embassy (https://embassy.dev/) as my async runtime. In my program I have two tasks: one data acquisition task, and a data processing task. I want the data gathered in the acquisition task to find its way inside the data processing task. Ideally, I want to only react on new data, as shown in the example below. What are some idiomatic ways to do so?
Here's a rough idea of how my code looks like:
```rust
#[embassy_executor::task]
async fn data_acquisition(mut used_peripherals: UsedPeripherals) {
    let data = sample_data(&mut used_peripherals).await;
    // Now I want to access the data in another task.
}

#[embassy_executor::task]
async fn data_processing() {
    // Somehow wait for new data.
    // Do stuff with the received data.
}
```
