What it reads

Cargo.toml, Cargo.lock and .cargo/config.toml.

Tier

Ordinary defect.

The tier bounds how severe a rule may be; its category bounds the tier.

Change it

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

rust-doctor --rule rust_doctor::cargo::unused_dependency=off .
rust-doctor --rule rust_doctor::cargo::unused_dependency=error .

Set it once in rust-doctor.toml
