Implementations

impl FieldRepetitionType

pub const REQUIRED: FieldRepetitionType = _

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

pub const OPTIONAL: FieldRepetitionType = _

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

pub const REPEATED: FieldRepetitionType = _

The field is repeated and can contain 0 or more values

pub const ENUM_VALUES: &'static [Self] = _

Trait Implementations

impl Clone for FieldRepetitionType

fn clone(&self) -> FieldRepetitionType

Returns a copy of the value.

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

Performs copy-assignment from source.

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

Formats the value using the given formatter.

impl From<&FieldRepetitionType> for i32

fn from(e: &FieldRepetitionType) -> i32

Converts to this type from the input type.

impl From<&i32> for FieldRepetitionType

fn from(i: &i32) -> Self

impl From<FieldRepetitionType> for i32

fn from(e: FieldRepetitionType) -> i32

Converts to this type from the input type.

impl From<Repetition> for FieldRepetitionType

fn from(value: Repetition) -> Self

Converts to this type from the input type.

impl From<i32> for FieldRepetitionType

fn from(i: i32) -> Self

Converts to this type from the input type.

impl Hash for FieldRepetitionType

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 Ord for FieldRepetitionType

fn cmp(&self, other: &FieldRepetitionType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for FieldRepetitionType

fn eq(&self, other: &FieldRepetitionType) -> 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 PartialOrd for FieldRepetitionType

fn partial_cmp(&self, other: &FieldRepetitionType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

fn read_from_in_protocol<T: TInputProtocol>( i_prot: &mut T, ) -> Result<FieldRepetitionType>

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.
