期货的Scala命名约定

Question

What is the naming convention in Scala for function returning result wrapped in Future? I have seen code like:

getResult
getResultF
getResultFtr

Or even

getResultFuture

If there is no specific convention then I would like to know what is practiced more.

Answer 1

I usually don't name methods returning Futures any differently. My reason is that this information is already present in the return type, and will be made clear by any decent IDE upon autocompletion.

One exception is in the presence of another similar method that doesn't return a Future but does everything synchronously. In that case, I like to clearly differentiate them:

def fooSync: A
def fooAsync: Future[A]

That's a pattern I've seen in plenty of libraries.
