Module std::panic

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

• 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
  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.
• always_abortExperimental
  Make 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
  Configure 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.
