error: lifetime may not live long enough

LL | Foo { x, y };

| ^ this usage requires that `'a` must outlive `'b`
|
|
|
|
|
= help: consider adding the following bound: `'a: 'b`
|
|
= note: requirement occurs because of the type `Cell<&u32>`, which makes the generic argument `&u32` invariant
|
|
= note: the struct `Cell<T>` is invariant over the parameter `T`
|
|
= help: see <https://doc.rust-lang.org/nomicon/subtyping.html> for more information about variance
