Enum target_spec::summaries::TargetFeaturesSummary

#[non_exhaustive]
pub enum TargetFeaturesSummary {
    Unknown,
    Features(BTreeSet<String>),
    All,
}

Available on crate feature summaries only.

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)

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.

Implementations

impl TargetFeaturesSummary

pub fn new(target_features: &TargetFeatures) -> Self

Creates a new TargetFeaturesSummary from a TargetFeatures.

pub fn to_target_features(&self) -> TargetFeatures

Converts self to a TargetFeatures instance.

Trait Implementations

impl Clone for TargetFeaturesSummary

fn clone(&self) -> TargetFeaturesSummary

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TargetFeaturesSummary

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TargetFeaturesSummary

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TargetFeaturesSummary

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>where
    D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<TargetFeaturesSummary> for TargetFeaturesSummary

fn eq(&self, other: &TargetFeaturesSummary) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TargetFeaturesSummary

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>where
    S: Serializer,

Serialize this value into the given Serde serializer.
