//! Defining the panic handler
//!
//! The panic handler can be defined through the `panic_fmt` [language item][1].
//! Make sure that the "abort-on-panic" feature of the cortex-m-rt crate is
//! disabled to avoid redefining the language item.
//!
//! [1]: https://doc.rust-lang.org/unstable-book/language-features/lang-items.html
