Module :: implements

Macro to answer the question: does it implement a trait?

This solution has a limitation:

• In case entity is a function and trait is Fn/FnMut/FnOnce which current entity does not implement you will get compile-time error instead of false.

Sample

``` rust use implements::*;

dbg!( implements!( 13i32 => Copy ) ); // < implements!( 13i32 => Copy ) : true dbg!( implements!( Box::new( 13i32 ) => Copy ) ); // < implements!( 13i32 => Copy ) : false ```

To add to your project

sh cargo add implements

Try out from the repository

sh git clone https://github.com/Wandalen/wTools cd wTools cd sample/rust/implements_trivial cargo run
