Struct Neg

Source
pub struct Neg;
Expand description

A Unary operation that will concurrently resolve a Future and neg its result.

§Example

use futures_executor::block_on;
use async_ops::Neg;

let a = async { 42 };

let result = async {
  async_ops::on(a).unary_op(Neg).await
};

assert_eq!(std::ops::Neg::neg(42), block_on(result));
