error[E0308]: mismatched types
--> $DIR/issue-79518-default_trait_method_normalization.rs:16:32

LL | Self::AssocInstance == [(); std::mem::size_of::<Self::Assoc>()];
| ------------------- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ expected associated type, found `[(); std::mem::size_of::<Self::Assoc>()]`
| |
| expected because this is `<Self as Foo>::Assoc`
|
= note: expected associated type `<Self as Foo>::Assoc`
found array `[(); std::mem::size_of::<Self::Assoc>()]`
= help: consider constraining the associated type `<Self as Foo>::Assoc` to `[(); std::mem::size_of::<Self::Assoc>()]` or calling a method that returns `<Self as Foo>::Assoc`
= note: for more information, visit https://doc.rust-lang.org/book/ch19-03-advanced-traits.html
