| //! Set the panicking behavior to halt |
| //! |
| //! This crate contains an implementation of `panic_fmt` that simply halt in an infinite loop. |
| //! |
| //! # Usage |
| //! |
| //! ``` ignore |
| //! #![no_std] |
| //! |
| //! extern crate panic_halt; |
| //! |
| //! fn main() { |
| //! panic!("argument is ignored"); |
| //! } |
| //! ``` |
| //! |
| //! # Breakable symbols |
| //! |
| //! With the panic handler being `#[inline(never)]` the symbol `rust_begin_unwind` will be |
| //! available to place a breakpoint on to halt when a panic is happening. |
