Enum parquet::basic::Repetition

pub enum Repetition {
    REQUIRED,
    OPTIONAL,
    REPEATED,
}

Representation of field types in schema.

Variants

REQUIRED

Field is required (can not be null) and each record has exactly 1 value.

OPTIONAL

Field is optional (can be null) and each record has 0 or 1 values.

REPEATED

Field is repeated and can contain 0 or more values.

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 Display for Repetition

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

Formats the value using the given formatter.

impl From<Repetition> for FieldRepetitionType

fn from(value: Repetition) -> Self

Converts to this type from the input type.

impl FromStr for Repetition

type Err = ParquetError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self>

Parses a string s to return a value of this type.

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 = ParquetError

The type returned in the event of a conversion error.

fn try_from(value: FieldRepetitionType) -> Result<Self>

Performs the conversion.

impl Copy for Repetition

impl Eq for Repetition

impl StructuralPartialEq for Repetition
