2/// Test if an item implements `Debug` trait.
3/// 
4/// ### Examples
5///
6/// - Debug item:
7/// 
8/// ```
9/// // either "test" or "all" features must be enabled
10/// #[cfg(any(feature = "test", feature = "all"))]
11/// {
12///     use cs_utils::test::implements_debug;
13///
14///     #[derive(Debug)]
15///     struct TestStruct {}
16/// 
17///     // compiles fine
18///     implements_debug(TestStruct {});
19/// }
20/// ```
21/// 
22/// - Non-Debug item:
23/// 
24/// ```compile_fail
25/// // either "test" or "all" features must be enabled
26/// #[cfg(any(feature = "test", feature = "all"))]
27/// {
28///     use cs_utils::test::implements_debug;
29///     
30///     // don't derive Debug
31///     struct TestStruct {}
32/// 
33///     // does not compile
34///     implements_debug(TestStruct {});
35/// }
36/// ```
