Function ffi_helpers::panic::recover_panic_message

pub fn recover_panic_message(e: Box<dyn Any + Send + 'static>) -> Option<String>

Try to recover the error message from a panic.

std::panic::catch_unwind() gives you a Box<Any + Send + 'static> instead of a concrete error type. This will attempt to downcast the error to various “common” panic error types, falling back to some stock message if we can’t figure out what the original panic message was.
