Not a defect when

The attribute comes from a macro that emits #[inline] uniformly on every trait method, where it is a harmless no-op on the declaration.

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.

What --scope contextual looks at to decide whether a change caused the finding.

Change it

Turn it off, or make it blocking, without touching the code it flags:

rust-doctor --rule clippy::inline_fn_without_body=off .
rust-doctor --rule clippy::inline_fn_without_body=error .

Set it once in rust-doctor.toml
