Struct LanguageStandardsSummary 

pub struct LanguageStandardsSummary {
    pub c: Option<ResolvedStandard<CStandard>>,
    pub cxx: Option<ResolvedStandard<CxxStandard>>,
    pub targets: BTreeMap<String, TargetStandardsSummary>,
}

Per-package language-standard summary carried by BuildConfiguration: package-level effective standards plus the effective values for every target. Values (not provenance) feed the fingerprint; the whole struct feeds cabin metadata / cabin explain build-config. Absent entries mean the language has no declared standard anywhere for that scope.

Fields

c: Option<ResolvedStandard<CStandard>>

cxx: Option<ResolvedStandard<CxxStandard>>

targets: BTreeMap<String, TargetStandardsSummary>

Implementations

impl LanguageStandardsSummary

pub fn from_package(package: &Package) -> Self

Compute the summary from a package’s declarations.

pub fn fingerprint_lines(&self) -> Vec<String>

Stable line serialization for the build-configuration fingerprint. Values only - provenance must not move the fingerprint, and absent standards (and the default gnu-extensions = false) contribute no line.

Trait Implementations

impl Clone for LanguageStandardsSummary

fn clone(&self) -> LanguageStandardsSummary

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LanguageStandardsSummary

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

Formats the value using the given formatter.

impl Default for LanguageStandardsSummary

fn default() -> LanguageStandardsSummary

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LanguageStandardsSummary

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for LanguageStandardsSummary

impl PartialEq for LanguageStandardsSummary

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for LanguageStandardsSummary

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
