Not a defect when

Emptying the vector is the intent and resize(0, value) was written deliberately for uniformity with neighboring resize calls, though clear() states it directly.

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

Set it once in rust-doctor.toml
