better-panic gives you pretty backtraces for panics.
It is inspired by Python tracebacks and tries to replicate them as well as possible. This is what it looks like:
Some of the code is based on the color-backtrace library.
The most common way to use it is to invoke the install function
which installs a panic handler. In debug builds the backtrace is shown
automatically, in release builds it's hidden by default.
better_panic::install();For more configuration see the Settings object.
- Colorize backtraces to be easier on the eyes
- Show source snippets if source files are found on disk
- Hide all the frames after the panic was already initiated
