Comparison with a type extreme, always constant

clippy::absurd_extreme_comparisons

Rewrite the comparison against the type's real range: as written it always yields the same answer.

Category: Correctness
Default level: warn
Tier: P1
Producer: Clippy
Diff scope: line

Not a defect when

The compared type is a platform-dependent alias such as usize or c_long, and the comparison deliberately detects the target's width, so it varies across targets even though it is constant on this one.

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

Set it once in rust-doctor.toml
