//! Redirecting `panic!` messages
//!
//! The `cortex-m-rt` crate provides two options to redirect `panic!` messages
//! through these two Cargo features:
//!
//! - `panic-over-semihosting`. `panic!` messages will be printed to the OpenOCD
//! console using semihosting. This is slow.
//!
//! - `panic-over-itm`. `panic!` messages will be send through the ITM port 0.
//! This is much faster but requires ITM support on the device.
//!
//! If neither of these options is specified then the `panic!` message will be
//! lost. Note that all `panic!`s will trigger a debugger breakpoint.
