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.
