Enum Cardinality 

pub enum Cardinality {
    Required,
    Optional,
    Vec,
    BoundedVec(u32),
}

How many times a field may appear.

Variants

Required

minOccurs=1, maxOccurs=1 — plain field.

Optional

minOccurs=0, maxOccurs=1 — Option<T>.

Vec

maxOccurs="unbounded" — Vec<T>.

BoundedVec(u32)

maxOccurs=N where N > 1 — Vec<T> with a documented upper bound.

Trait Implementations

impl Clone for Cardinality

fn clone(&self) -> Cardinality

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cardinality

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

Formats the value using the given formatter.

impl PartialEq for Cardinality

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