pub enum Repetition {
    Required,
    Optional,

Trait Implementations

impl Clone for Repetition

fn clone(&self) -> Repetition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Repetition

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

Formats the value using the given formatter.

impl From<Repetition> for FieldRepetitionType

fn from(repetition: Repetition) -> Self

Converts to this type from the input type.

impl Hash for Repetition

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 Repetition

fn eq(&self, other: &Repetition) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<FieldRepetitionType> for Repetition

type Error = Error

The type returned in the event of a conversion error.

fn try_from(repetition: FieldRepetitionType) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Repetition

impl Eq for Repetition

impl StructuralPartialEq for Repetition
