Not a defect when
The formatted value only looks like self but is a field or deref target with its own implementation of that trait, so no recursion occurs.
What it reads
Clippy, with the compiler behind it. The only pass that compiles.
Tier
Serious: worth interrupting other work for.
The tier bounds how severe a rule may be; its category bounds the tier.Diff scope
The changed line itself.

Turn it off, or make it blocking, without touching the code it flags:
rust-doctor --rule clippy::recursive_format_impl=off .
rust-doctor --rule clippy::recursive_format_impl=error .
