Struct Neg

pub struct Neg;

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));

Trait Implementations

impl<Operand: Future> Unary<Operand> for Neg

where Operand::Output: Neg,

type Output = AsyncNeg<Operand>

The resulting type after applying the unary operation.

fn op(operand: Operand) -> Self::Output

Do the unary operation on the given operand.
