 A library that provides `print!`, `println!`, `dbg!` implementations and
 logging capabilities for Espressif devices.

 - Supports different communication methods:
-    - UART (Default)
-    - JTAG-Serial (Only available in ESP32-C3, ESP32-C6, ESP32-H2, ESP32-S3)
-    - No-op: Turns printing into a no-op

+If you experience linker errors, make sure you have _some_ reference to `esp_println` in your code.
 If you don't use `esp_println` directly, you'll need to add e.g. `use esp_println as _;` to your
 import statements. This ensures that the global logger will not be removed by the compiler.
