Trait Implementations

impl Clone for XmlTypeCardinality

fn clone(&self) -> XmlTypeCardinality

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for XmlTypeCardinality

impl Debug for XmlTypeCardinality

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

Formats the value using the given formatter.

impl Default for XmlTypeCardinality

fn default() -> XmlTypeCardinality

Returns the “default value” for a type.

impl Display for XmlTypeCardinality

impl Eq for XmlTypeCardinality

impl Hash for XmlTypeCardinality

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,

impl PartialEq for XmlTypeCardinality

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