Struct Panic

pub struct Panic(/* private fields */);

An error representing a panic carrying the message as payload.

To capture panics, register the hook using set_panic_hook.

Example

use relay_ffi::{catch_unwind, with_last_error, Panic};

#[catch_unwind]
unsafe fn panics() {
    panic!("this is fine");
}

relay_ffi::set_panic_hook();

unsafe { panics() };

with_last_error(|error| {
    if let Some(panic) = error.downcast_ref::<Panic>() {
        println!("{}", panic.description());
    }
});

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

Formats the value using the given formatter.

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>)
