Enum InterfaceRequirement 

pub enum InterfaceRequirement<S> {
    None,
    Requirement(StandardRequirement<S>),
}

One declared interface-standard value: either a requirement or the explicit none, meaning the target’s headers are not consumable from that language. Implements the explicit interface declaration decl_L(t) of spec D6 (docs/design/standard-compatibility/spec.md); D6’s ⊥ (no declaration) is an absent Option<InterfaceRequirement> at the use sites.

Variants

None

The target’s headers are not consumable from this language: the declared "none" of spec D6, which D9 row 1 maps to the unsatisfiable requirement (crate::standard_compatibility::Requirement::Forbidden).

Requirement(StandardRequirement<S>)

Implementations

impl<S> InterfaceRequirement<S>

pub fn min(self) -> Option<S>

The minimum standard, when this is a requirement.

Trait Implementations

impl<S: Clone> Clone for InterfaceRequirement<S>

fn clone(&self) -> InterfaceRequirement<S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: Copy> Copy for InterfaceRequirement<S>

impl<S: Debug> Debug for InterfaceRequirement<S>

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

Formats the value using the given formatter.

impl<'de, S: Deserialize<'de>> Deserialize<'de> for InterfaceRequirement<S>

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<S: Display> Display for InterfaceRequirement<S>

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

Formats the value using the given formatter.

impl<S: Eq> Eq for InterfaceRequirement<S>

impl<S: PartialEq> PartialEq for InterfaceRequirement<S>

fn eq(&self, other: &InterfaceRequirement<S>) -> 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<S: Serialize> Serialize for InterfaceRequirement<S>

fn serialize<Ser>(&self, serializer: Ser) -> Result<Ser::Ok, Ser::Error>

where Ser: Serializer,

Serialize this value into the given Serde serializer.
