I was wondering what this error meant while creating a case in a visit
statement?
This is an example of the case causing it:
case (Statement) `<Lifetime lt>: <Statement stmt>` => (Statement) `<Statement stmt>`
My goal with this is just to delete the Lifetime
statement together with the following colon.
Thank you for reporting this and many apologies for this brutal and incomprehensible message. The error means that there is a parse error in one of the concrete fragments between ` and `.
We will improve the reporting of this kind of errors!
