pub trait NegAssign {
// Required method
fn neg_assign(&mut self);
}Expand description
Compound negation and assignment.
§Examples
use rug::ops::NegAssign;
struct I(i32);
impl NegAssign for I {
fn neg_assign(&mut self) {
self.0 = -self.0;
}
}
let mut i = I(42);
i.neg_assign();
assert_eq!(i.0, -42);Required Methods§
sourcefn neg_assign(&mut self)
fn neg_assign(&mut self)
Peforms the negation.
§Examples
use rug::ops::NegAssign;
use rug::Integer;
let mut i = Integer::from(-42);
i.neg_assign();
assert_eq!(i, 42);
