error[E0369]: binary operation `==` cannot be applied to type `Vec<Foo>`
--> $DIR/eq-vec.rs:11:5
|
LL | assert_eq!(vec1, vec2);
| ^^^^^^^^^^^^^^^^^^^^^^

| Vec<Foo>
| Vec<Foo>
|
note: an implementation of `PartialEq` might be missing for `Foo`
--> $DIR/eq-vec.rs:3:5
|
LL | enum Foo {
| ^^^^^^^^ must implement `PartialEq`
= note: this error originates in the macro `assert_eq` (in Nightly builds, run with -Z macro-backtrace for more info)
help: consider annotating `Foo` with `#[derive(PartialEq)]`

LL + #[derive(PartialEq)]
LL | enum Foo {
