Do not provide suggestions when the spans come from expanded code that doesn't point at user code by oli-obk · Pull Request #109082 · rust-lang/rust (original) (raw)

coming from proc-macros pointing at attribute.

Effectively, unless the proc-macro keeps user spans,
suggestions will not be produced for the code they
produce.
