+// Pick one of these panic handlers:

+// `panic!` halts execution; the panic message is ignored
+use panic_halt as _;

+// Reports panic messages to the host stderr using semihosting
+// NOTE to use this you need to uncomment the `panic-semihosting` dependency in Cargo.toml
+// use panic_semihosting as _;

+// Logs panic messages using the ITM (Instrumentation Trace Macrocell)
+// NOTE to use this you need to uncomment the `panic-itm` dependency in Cargo.toml
+// use panic_itm as _;
