Function implements_debug

pub fn implements_debug<T: Debug>(item: T) -> T

Test if an item implements Debug trait.

Examples

• Debug item:

// either "test" or "all" features must be enabled
#[cfg(any(feature = "test", feature = "all"))]
{
    use cs_utils::test::implements_debug;

    #[derive(Debug)]
    struct TestStruct {}
 
    // compiles fine
    implements_debug(TestStruct {});
}

• Non-Debug item:

// either "test" or "all" features must be enabled
#[cfg(any(feature = "test", feature = "all"))]
{
    use cs_utils::test::implements_debug;
     
    // don't derive Debug
    struct TestStruct {}
 
    // does not compile
    implements_debug(TestStruct {});
}
