Enum Repetition

pub enum Repetition {
    Required,
    Optional,
    Repeated,
}

Variants

Required

When the field has no null values

Optional

When the field may have null values

Repeated

When the field may be repeated (list field)

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

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 TryFrom<FieldRepetitionType> for Repetition

type Error = ParquetError

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
