Function safina::select_abcde

pub async fn select_abcde<A, B, C, D, E, FutA, FutB, FutC, FutD, FutE>(
    a: FutA, 
    b: FutB, 
    c: FutC, 
    d: FutD, 
    e: FutE
) -> OptionABCDE<A, B, C, D, E> where
    FutA: Future<Output = A> + Send + 'static,
    FutB: Future<Output = B> + Send + 'static,
    FutC: Future<Output = C> + Send + 'static,
    FutD: Future<Output = D> + Send + 'static,
    FutE: Future<Output = E> + Send + 'static, 

Awaits the futures and returns the value from the one that completes first.

First moves them to the heap, to make them Unpin. Use SelectFuture::new to avoid allocating on the heap.
