Function cs_utils::test::implements_send

pub fn implements_send<T: Send>(item: T) -> T

Test if an item implements Send trait.

Examples

• Send item:

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

    // Send is auto implemented
    struct TestStruct {}
 
    // compiles fine
    implements_send(TestStruct {});
}

• Non-Send item:

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