Function or 

pub fn or<T, S, R>(reactors: R) -> <OrChain<R> as IntoReactor<T, S>>::Reactor
where
    OrChain<R>: IntoReactor<T, S>,
    T: Clone,

Reacts with the given reactors in order until the first response.

This function accepts a type R for which OrChain<R> implements IntoReactor. OrChain implements this trait for collection types, most notably non-unary tuple types and Vec of Reactor types.

The constructed reactor returns either the first response from the given reactors or the error from the last reactor. See also the Reactor::or function.
