Enum TargetFeaturesSummary

source
#[non_exhaustive]
pub enum TargetFeaturesSummary { Unknown, Features(BTreeSet<String>), All, }
Available on crate feature summaries only.
Expand description

An owned, serializable version of TargetFeatures.

This type can be serialized and deserialized using serde.

Requires the summaries feature to be enabled.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Unknown

The target features are unknown.

This is the default.

§

Features(BTreeSet<String>)

Only match the specified features.

§

All

Match all features.
