Print backtrace with Display::fmt

[musjj]

I have an error like this:

#[derive(thiserror::Error, Debug)]
pub enum MyError {
    ...

    #[error(transparent)]
    Other(#[from] eyre::Error),
}

I want to print the error along with the backtrace and it seems the only way to do it is to use Debug::fmt:

if let Err(e) = trigger_error() {
    tracing::error!("{e:?}");
}

But this wraps the error awkwardly like this:

Other(hello i'm error

Location:                                                                                                                                                                           
    src/main.rs:1:1) 

If you use Display::fmt you can take advantage of thiserror's #[error(transparent)] feature, which gets you a cleaner output, but you lose the backtrace.

So it would be nice if there's an option for including the backtrace in the Display::fmt output.
