Enum Features 

pub enum Features {
    Default,
    All,
    None,
}

Which Cargo feature set a compilation used, or that a code site needs to be compiled at all.

Not ordered by “more features”: --all-features does not subsume the default set, because code behind cfg(not(feature = …)) is compiled by exactly one of them. The default-features CI job exists because three -D warnings errors had rotted in code that --all-features structurally cannot see.

Variants

Default

The crate’s default feature set.

All

--all-features.

None

--no-default-features.
