> - 运算符在RxSwift中意味着什么？它在哪里记录？

Question

I've seen the >- operator in various code fragments involving RxSwift (eg https://github.com/ReactiveX/RxSwift/issues/35 ), but can't find any documentation on it. What does it mean?

Here's an example:

combineLatest(emailIsValid, passwordIsValid)
    >- and
    >- signupButton.rx_subscribeEnabledTo
    >- disposeBag.addDisposable

Answer 1

The >- operator is called the "pipe-forward operator" and it was removed in this commit in favor of protocol extensions, once they were possible in Swift.

It was just the best way to do it at that moment, given Swift's abilities.
