3// The warning `clippy::op_ref` is disabled to allow efficient operator arithmetic of structs that
4// implement the `Copy` trait.
5//
6// ```
7// let opening_0: PedersenOpening = PedersenOpening::new_rand();
8// let opening_1: PedersenOpening = PedersenOpening::new_rand();
9//
10// // since PedersenOpening implement `Copy`, `opening_0` and `opening_1` will be copied as
11// // parameters before `opening_sum` is computed.
12// let opening_sum = opening_0 + opening_1;
13//
14// // if passed in as references, the extra copies will not occur
15// let opening_sum = &opening_0 + &opening_1;
16// ```
17//
18// `clippy::op_ref` is turned off to prevent clippy from warning that this is not idiomatic code.
