Function cs_utils::test::implements_sync

pub fn implements_sync<T: Sync>(item: T) -> T

Test if an item implements Sync trait.

Examples

• Sync item:

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

    // Sync is auto implemented
    struct TestStruct {}
 
    // compiles fine
    implements_sync(TestStruct {});
}

• Non-Sync item:

// either "test" or "all" features must be enabled
#[cfg(any(feature = "test", feature = "all"))]
{
    use cs_utils::test::implements_sync;
 
    struct TestStruct {
        // make it not Sync
        rc: std::rc::Rc<u8>,
    }
 
    // does not compile
    implements_sync(TestStruct {});
}
