## Structs§

AssertUnwindSafe

  A struct providing information about a panic.

## Enums§

BacktraceStyleExperimental
  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§

catch_unwind
  Invokes a closure, capturing the cause of an unwinding panic if one occurs.
panic_any
  Panics 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.
abort_unwindExperimental
  Invokes a closure, aborting if the closure unwinds.
always_abortExperimental
  Makes all future panics abort directly without running the panic hook or unwinding.
get_backtrace_styleExperimental
  Checks whether the standard library’s panic hook will capture and print a backtrace.
set_backtrace_styleExperimental
  Configures whether the default panic hook will capture and display a backtrace.
update_hookExperimental
  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.

## Type Aliases§
