I have the following types (basically a vector that only returns references and a type with 2 vecors that returns a tuple of references: struct VecValues<A> { values: Vec<A> } impl<A> VecValues<A> { fn get(&self, index: usize) -> &A { &self.values[index] } } struct ZippedValue…

But then I cannot implement ZipValues so that it returns (&A,&B) (because it then must return a reference). But with your tips I found a solution: trait Values<'a> { type Item: 'a; fn get(&'a self, index: usize) -> Self::Item; } struct VecValues<A> { values: Vec<A> } impl<A> VecValue…
