Struct DependencyAttributes 

pub struct DependencyAttributes {
    pub kind: DependencyKind,
    pub impl_c: Option<CStandard>,
    pub impl_cxx: Option<CxxStandard>,
    pub decl_c: Option<InterfaceRequirement<CStandard>>,
    pub decl_cxx: Option<InterfaceRequirement<CxxStandard>>,
}

Spec D6: the resolved attributes of a dependency target, as produced by the manifest layer (precedence and inheritance already applied). Per D6’s population contract, impl_* is Some exactly when the target itself implements the language - a package-level implementation default alone never populates it.

Fields

kind: DependencyKind

Spec D6: kind(t).

impl_c: Option<CStandard>

Spec D6: impl_C(t); None is ⊥ (the target does not implement C).

impl_cxx: Option<CxxStandard>

Spec D6: impl_C++(t); None is ⊥.

decl_c: Option<InterfaceRequirement<CStandard>>

Spec D6: decl_C(t); None is ⊥ (no explicit interface declaration), Some(InterfaceRequirement::None) the declared "none", and Some(InterfaceRequirement::Requirement(..)) a declared minimum.

decl_cxx: Option<InterfaceRequirement<CxxStandard>>

Spec D6: decl_C++(t).

Trait Implementations

impl Clone for DependencyAttributes

fn clone(&self) -> DependencyAttributes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DependencyAttributes

impl Debug for DependencyAttributes

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

Formats the value using the given formatter.

impl Eq for DependencyAttributes

impl PartialEq for DependencyAttributes

fn eq(&self, other: &DependencyAttributes) -> 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.
