Struct Panic 

pub struct Panic { /* private fields */ }

Panic info gathered as one record

Contains panic’s location, message or raw payload, and backtrace, if collected

Implementations

impl Panic

pub fn location(&self) -> Option<&OwnedLocation>

Panic location, if original std::panic::PanicHookInfo provided one

pub fn message(&self) -> &str

Original panic message which was supplied to std::panic! macro

If panic was raised using std::panic::panic_any with non-string payload, this function returns substitute message

pub fn raw_payload(&self) -> Option<&Box<dyn Any + Send + 'static>>

Raw panic payload if it wasn’t recognized as string-like message and converted to it

pub fn backtrace(&self) -> &Backtrace

Panic’s backtrace gathered from within panic hook

pub fn into_raw_payload(self) -> Box<dyn Any + Send + 'static>

Transforms panic info into raw panic payload. If it’s a string-like message, it gets re-wrapped again.

Useful when you need something like rethrowing panic

pub fn display_with_backtrace(&self) -> impl Display + '_

Produces std::fmt::Display’able object which displays panic’s message, location and short backtrace, if captured

pub fn display_with_backtrace_style( &self, style: BacktraceStyle, ) -> impl Display + '_

Produces std::fmt::Display’able object which displays panic’s message, location and backtrace, if captured, with specified style

Trait Implementations

impl Debug for Panic

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Panic

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Displays panic’s message and location

To display full panic info including backtrace, use Panic::display_with_backtrace

impl Error for Panic

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
