Expand description

Panic support in the standard library.

## Structs

- AssertUnwindSafe
  A simple wrapper around a type to assert that it is unwind safe.
- Location
  A struct containing information about the location of a panic.
- PanicInfo
  A struct providing information about a panic.

## Enums

- BacktraceStyle Experimental
  The configuration for whether and how the default panic hook will capture and display the backtrace.

## Traits

- RefUnwindSafe
  A marker trait representing types where a shared reference is considered unwind safe.
- UnwindSafe
  A marker trait which represents “panic safe” types in Rust.

## Functions

- always_abort Experimental
  Make all future panics abort directly without running the panic hook or unwinding.
- get_backtrace_style Experimental
  Checks whether the standard library’s panic hook will capture and print a backtrace.
- set_backtrace_style Experimental
  Configure whether the default panic hook will capture and display a backtrace.
- update_hook Experimental
  Atomic combination of `take_hook` and `set_hook`. Use this to replace the panic handler with a new panic handler that does something and then executes the old handler.
- catch_unwind
  Invokes a closure, capturing the cause of an unwinding panic if one occurs.
- panic_any
  Panic the current thread with the given message as the panic payload.
- resume_unwind
  Triggers a panic without invoking the panic hook.
- set_hook
  Registers a custom panic hook, replacing the previously registered hook.
- take_hook
  Unregisters the current panic hook and returns it, registering the default hook in its place.
