v0.9.1 does not compile when default-features = false

Hi, as the title suggests, version 0.9.1 does not compile when default-features = false. Looks like an import is missing.

Hi thanks the report, there were some conditional imports wrong, it's fixed with 0.9.2 and I added a test for it.

Thanks for the quick fix!
