boost split with a single character or just one string

I wish to split a string on a single character or a string. I would like to use boost::split since boost string is our standard for basic string handling (I don't wish to mix several techniques).

In the single character case I could do split(vec,str,is_any_of(':')) but I'd like to know if there is a way to specify just a single character. It may improve performance, but more importantly I think the code would be clearer with just a single character, since is_any_of conveys a different meaning that what I want.

For matching against a string I don't know what syntax to use. I don't wish to to construct a regex; some simple syntax like split(vec,str,match_str("::") would be good.

On the simple token, I would just leave is_any_of as it is quite easy to understand what is_any_of( single_option ) means. If you really feel like changing it, the third element is a functor, so you could pass an equals functor to the split function.

That approach will not really work with multiple tokens, as the iteration is meant to be characater by character. I don't know the library enough to offer prebuilt alternatives, but you can implement the functionality on top of split_iterators
