How to use Yard to document enumerable type and the types that they contain?

Question

Using the ruby Yard doc tool I can write

# @param bar [String]
def foo(bar)
end

however if the parameter is an enumerable

# @param bar [Enumerable[String]]
def foo(bar)
end

Is the above the correct way or not?

Answer 1

Do it like this:

# @param [Enumerable<String>] bar
def foo(bar)
end
