error: lifetime may not live long enough

| has type `TwoThings<'_, '1>`

LL | SameLifetime(ctx);
|
|
| ^^^ this usage requires that `'1` must outlive `'2`
|
|
|
|
|
= note: requirement occurs because of the type `TwoThings<'_, '_>`, which makes the generic argument `'_` invariant
|
|
= note: the struct `TwoThings<'a, 'b>` is invariant over the parameter `'a`

= help: see <https://doc.rust-lang.org/nomicon/subtyping.html> for more information about variance
