1.0.0[−][src]Trait tract_hir::internal::tract_downcast_rs::__std::ops::Neg
The unary negation operator -
.
Examples
An implementation of Neg
for Sign
, which allows the use of -
to
negate its value.
use std::ops::Neg; #[derive(Debug, PartialEq)] enum Sign { Negative, Zero, Positive, } impl Neg for Sign { type Output = Sign; fn neg(self) -> Self::Output { match self { Sign::Negative => Sign::Positive, Sign::Zero => Sign::Zero, Sign::Positive => Sign::Negative, } } } // A negative positive is a negative. assert_eq!(-Sign::Positive, Sign::Negative); // A double negative is a positive. assert_eq!(-Sign::Negative, Sign::Positive); // Zero is its own negation. assert_eq!(-Sign::Zero, Sign::Zero);
Associated Types
type Output
The resulting type after applying the -
operator.
