Enum rustc_lint::session::config::UnstableFeaturesUnstable

pub enum UnstableFeatures {
    Disallow,
    Default,
    Cheat,
}

Variants

Disallow	Hard errors for unstable features are active, as on beta/stable channels.
Default	Use the default lint levels
Cheat	Errors are bypassed for bootstrapping. This is required any time during the build that feature-related lints are set to warn or above because the build turns on warnings-as-errors and uses lots of unstable features. As a result, this this is always required for building Rust itself.
