The allow-by-default lint missing_copy_implementations does not honor !Copy impls #101980
Description
I would expect the following code to compile successfully since we explicitly opt out of implementing Copy:
#![feature(negative_impls)]
#![deny(missing_copy_implementations)]
#![crate_type = "lib"]
pub struct Struct {
pub field: i32,
}
impl !Copy for Struct {}However, the code fails to compile with the following error message:
error: type could implement `Copy`; consider adding `impl Copy`
--> src/lib.rs:5:1
