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".

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,
