Trait HasNeg 

pub trait HasNeg<O, A> {
    // Required method
    fn neg(operand_type: O) -> (O, A);
}

Vars support this unary operator when the underlying signature has the appropriate operation.

Required Methods

fn neg(operand_type: O) -> (O, A)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
