`clippy::panic`

Return an error instead of aborting the process on an input the caller can recover from.

What it reads

Clippy, with the compiler behind it. The only pass that compiles.

Lowest tier: real, and rarely urgent.

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

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

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