= note: `#[deny(clippy::incorrect_clone_impl_on_copy_type)]` on by default
= note: this error originates in the derive macro `Derivative` (in Nightly builds, run with -Z macro-backtrace for more info)
error: could not compile `test_derivative` (lib) due to previous error
To Reproduce
Cargo.toml:
[package]
name = "test_derivative"
version = "0.1.0"
edition = "2021"
[dependencies]
derivative = "2.2.0"rust-toolchain.toml
[toolchain]
channel = "nightly-2023-07-03"
components = ["clippy", "rustfmt"]
profile = "default"src/lib.rs
use derivative::Derivative;
use std::marker::PhantomData;
#[derive(Derivative)]
#[derivative(Copy(bound = ""))]
#[derivative(Clone(bound = ""))]
pub struct Id<T> {
value: u32,
marker: PhantomData<T>,
}Expected behavior
No clippy lint triggered.
