Trait core::ops::Neg
[−]
[src]
pub trait Neg {
type Output;
fn neg(self) -> Self::Output;
}The Neg trait is used to specify the functionality of unary -.
Examples
A trivial implementation of Neg. When -Foo happens, it ends up calling
neg, and therefore, main prints Negating!.
use std::ops::Neg; struct Foo; impl Neg for Foo { type Output = Foo; fn neg(self) -> Foo { println!("Negating!"); self } } fn main() { -Foo; }
