PanicInfo get message in rust stable?

[andreeaflorescu]

Hey, I was wondering if there is any plan in having the method message from PanicInfo available in rust stable. The documentation points to an issue that is closed (#44489).

Related to the following issues in Firecracker:

• pretty-printing panics
• user inquiry

Is there another recommended way to get the panic information? I was also thinking about replacing the panic_hook with catch_unwind but we might get into problems if the external crates that we are using are implementing panic with abort.

IIRC PanicInfo implement Display which means you can either do println!("{}", panicinfo) or let info = panicinfo.to_string(). I guess message will be removed therefore.

edit: Display does indeed print the message but will prepend some text (https://doc.rust-lang.org/1.29.0/src/core/panic.rs.html#136), you might be able to remove that?! Not sure though.

I can hack my way around this. Thanks for the response.
