//! Changing the panicking behavior
//!
//! The easiest way to change the panicking behavior is to use a different [panic handler crate][0].

#![no_main]
#![no_std]

// 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 _;
