1 error[E0053]: method `jumbo` has an incompatible type for trait
2 --> $DIR/impl-method-mismatch.rs:7:5
4 LL | fn jumbo(&self, x: &usize) -> usize;
5 | ------------------------------------ type in trait
7 LL | unsafe fn jumbo(&self, x: &usize) { *self + *x; }
8 | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ expected normal fn, found unsafe fn
10 = note: expected fn pointer `fn(&usize, &usize) -> usize`
11 found fn pointer `unsafe fn(&usize, &usize)`
