Add second message for LiveDrop errors#73515

pvdrz · 2020-06-19T20:07:42Z

This is an attempt to fix #72907 by adding a second message to the LiveDrop diagnostics. Changing from this

error[E0493]: destructors cannot be evaluated at compile-time
 --> src/lib.rs:7:9
  |
7 |     let mut always_returned = None;
  |         ^^^^^^^^^^^^^^^^^^^ constants cannot evaluate destructors

error: aborting due to previous error

to this

error[E0493]: destructors cannot be evaluated at compile-time
  --> foo.rs:6:9
   |
6  |     let mut always_returned = None;
   |         ^^^^^^^^^^^^^^^^^^^ constants cannot evaluate destructors

10 |         always_returned = never_returned;
   |         --------------- value is dropped here

~~I think what you want is !term_span.is_dummy() at which point you should be able to not do this branch at all, as the diagnostics system can handle dummy spans I think~~

Oh, this is checking the span length. Why are you doing this?

The ui test diffs seem good to me and you can probably just bless them.

Can you also add a test showing your example in the PR post?

I was just following @ecstatic-morse suggestion: #72907 (comment)

Also without it there are a lot of overlapping messages, let me get you an example

Update: Nevermind, apparently I was looking a the diffs instead of the actual errors 🤦
