lifetime bound on associated type is rejected although it seems valid

Question

I have a piece of code that does not compile and that can be reduced to this snippet:

use std::error::Error;
use std         


        

Answer 1

I'm still not sure why, but it seems just removing the 'static bound on the error worked?
