RS.CLIPPY.CLONE_ON_COPY

Using `clone` on a `Copy` type

This checker is a Clippy lint created by The Rust Project Contributors. The documentation shown here is a copy of the original documentation for: clone_on_copy. Copyright ©2025 The Rust Team. All rights reserved.

What it does

Checks for usage of .clone() on a Copy type.

Why is this bad?

The only reason Copy types implement Clone is for generics, not for using the clone method on a concrete type.

Example

42u64.clone();
