for-tests = quickcheck
serialize-abomonation = abomonation

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

abomonation serialize-abomonation?
quickcheck for-tests?
