Maybe you could also clarify the output syntax here.
/// The anonymous type of a function declaration/definition. Each
/// function has a unique type, which is output (for a function

I think you can get away with just writing it on two lines, which saves a little space:
fn foo() -> i32 { 1 }
let bar = foo; // bar: fn() -> i32 {foo}

Add examples to `TyKind::FnDef` and `TyKind::FnPtr` docs This adds two examples to the docs of `TyKind::FnDef` and `TyKind::FnPtr`. I found these two types a bit confusing when I learned about them and I think adding these examples might help others.
