In order to get the lifetimes right I already minified my problem: struct A { data: [u8; 40] } struct B<'a> { borrow: &'a A } trait C<'b> { fn new_c_implementor(borrow: &'b A) -> Box<dyn C + 'b> where Self: Sized; } impl<'a> C<'a> for B<'a> { fn new_c_implementor(borrow: &'a A) ->…

I actually came up with a different solution from the 2 answers, which let me remove the generic lifetime on the Trait, so I just went with that. impl C for B<'_> { fn new_c_implementor(borrow: &A) -> Box<dyn C + '_> where Self: Sized { Box::new(B { borrow }) } }…

I think the solution by moving an early bound to late bound via closures deserves a compiler hint fix as the compiler suggests in this case.
