It seems to work on optional dependencies, not on features - is this intended?

How to reproduce (on MacOS, Rustc version 1.43.1, cargo-all-features version 1.2.0)

git clone https://github.com/crates-io/prodash
cd prodash
cargo build-all-features

What's expected is that it only activates features, along with their dependencies:

It seems to activate optional dependencies instead, along with all their permutations.

It should be running permutations of all optional dependencies and features: https://github.com/frewsxcv/cargo-all-features/blob/master/src/features_finder.rs

I just ran your "How to reproduce" steps and it seems to be picking up the features. Are you interested in having it not test optional dependencies?

[Byron]

Interesting! I never waited long enough to see it pick up features.
Indeed it was surprising to me given the name of the program, and I didn't know that valid features are also optional dependencies.

From my own experience, I think it would have been enough to only test features, and not optional dependencies. The latter would be nice at least to opt-out of.

i included optional dependencies because i've seen cases in the rust ecosystem use optional dependencies like features. and conceptually, they're essentially feature flags you need to invoke with --features <optional depedency>. in any case: #3
