It looks like rust-analyzer's custom parser does not support leading | in patterns. I filed an issue here. In the meantime I recommend removing the leading | and ignoring that code by placing // prettier-ignore above it.

This issue has been fixed in rust-analyzer. From what I understand the fix should be part of next week's release, or tomorrow if you use rust-analyzer nightly.
