1 error: lifetime may not live long enough
2 --> $DIR/implied-bounds-unnorm-associated-type-2.rs:19:5
5 | -- -- lifetime `'b` defined here
7 | lifetime `'a` defined here
9 | ^^^^^^^^^^^^^^^ requires that `'b` must outlive `'a`
11 = help: consider adding the following bound: `'b: 'a`
12 = note: requirement occurs because of a function pointer to `f`
13 = note: the function `f` is invariant over the parameter `'a`
14 = help: see <https://doc.rust-lang.org/nomicon/subtyping.html> for more information about variance
