Enum MetadataCardinality 

#[non_exhaustive]
pub enum MetadataCardinality {
    Single,
    Repeatable,
}

Whether a property accepts at most one assertion or repeated assertions.

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.

Single

Zero or one assertion on a target.

Repeatable

Zero or more assertions on a target.

impl Eq for MetadataCardinality

impl Hash for MetadataCardinality

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MetadataCardinality

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