Hello Rust friends. Is it bad to implement Add and then use this boilerplate for AddAssign? impl AddAssign for Foo { fn add_assign(&mut self, rhs: Self) { *self = *self + rhs; } }

Are there any types that implement both Add and AddAssign for which the above would not be a valid impl of AddAssign, i.e., can this be treated as an AddAssign "law"?
It'd always be *valid*, but for any type which heap allocates it'd be pretty problematic

Maybe unpopular take: "If x += 1 is equivalent to x = x + 1 you should just write the latter"
