-/// Configuration options used for conditional compilition on items with `cfg` attributes.
-/// We have two kind of options in different namespaces: atomic options like `unix`, and
-/// key-value options like `target_arch="x86"`.
-///
-/// Note that for key-value options, one key can have multiple values (but not none).
-/// `feature` is an example. We have both `feature="foo"` and `feature="bar"` if features
-/// `foo` and `bar` are both enabled. And here, we store key-value options as a set of tuple
-/// of key and value in `key_values`.
-///
-/// See: https://doc.rust-lang.org/reference/conditional-compilation.html#set-configuration-options
