 By default, checking is done on all features except features named `unstable`, `nightly`, `bench`, `no_std`, or ones with prefix `_`, `unstable-`, or `unstable_`, as such names are commonly used for private or unstable features.
 
 This behaviour can be overriden. Checked feature set can be changed to:

+- _all_ the features, selected with `--all-features`,
 - only the crate's default features, selected with `--default-features`,
 - empty set, selected with `--only-explicit-features`.
 
 Additionally, features can be enabled one-by-one, using flags `--features`, `--baseline-features` and `--current-features`.
 
 For example, consider crate [serde](https://github.com/serde-rs/serde), with the following features (per v1.0.163):

 - `std` - the crate's only default feature,
 - `alloc`, `derive`, `rc` - optional features,
 - `unstable` - a feature that possibly breaks semver.
