Macro impl_wrapper_unary 

macro_rules! impl_wrapper_unary {
    ($s:ident.$field:ident { $($op:ident.$call:ident),* $(,)?}) => { ... };
    ($s:ident { $($op:ident.$call:ident),* $(,)?}) => { ... };
    (@impl $s:ident::$op:ident.$call:ident($field:ident)) => { ... };
    (@impl $s:ident::$op:ident.$call:ident(0)) => { ... };
}

the [impl_wrapper_unary!] macro implements binary operations for a wrapper type.

Syntax

For tuple structs:

impl_wrapper_unary! {
   ${struct} { Op1.call, Op2.call, ... }
}

For structs with named fields:

impl_wrapper_unary! {
    ${struct}.${field} { Op1.call, Op2.call, ... }
}

Note: The target struct must have exactly one field;
