Trait Unary

pub trait Unary<Operand> {
    type Output;

    // Required method
    fn op(operand: Operand) -> Self::Output;
}

Trait that represents an unary operation on the operand of type Operand that returns the result of type Output.

See Async::unary_op.

Required Associated Types

type Output

The resulting type after applying the unary operation.

Required Methods

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

Do the unary operation on the given operand.

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.

Implementors

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

where Operand::Output: Neg,

type Output = AsyncNeg<Operand>

impl<Operand: Future> Unary<Operand> for Not

where Operand::Output: Not,

type Output = AsyncNot<Operand>
