A common pattern in Arduino C++ sketches is the use of Serial.print() or Serial.println() to debug problems.
What is the corresponding Rust idiom when programming for the Arduino Uno?
What is the Rust equivalent of Serial.println from the Arduino C++ API?

One technique involves the use of arduino_hal::default_serial! and ufmt::writeln!
For setup:
let dp = arduino_hal::Peripherals::take().unwrap();
let pins = arduino_hal::pins!(dp);
let mut serial = arduino_hal::default_serial!(dp, pins, 115200);
and when you need to print
ufmt::uwriteln!(&mut serial, "{} bytes available", count);
The uwriteln! macro is not as powerful as format! or println! from std. For instance, it does not support {:02x} for integers.
