Enum parquet_format::Type

pub enum Type {
    Boolean,
    Int32,
    Int64,
    Int96,
    Float,
    Double,
    ByteArray,
    FixedLenByteArray,
}

Types supported by Parquet. These types are intended to be used in combination with the encodings to control the on disk storage format. For example INT16 is not included as a type since a good encoding of INT32 would handle this.

Variants

Boolean

Int32

Int64

Trait Implementations

impl Clone for Type

pub fn clone(&self) -> Type

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Type

impl Debug for Type

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

Formats the value using the given formatter.

impl Eq for Type

impl Hash for Type

pub fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl Ord for Type

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

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Type> for Type

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

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

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<Type> for Type

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

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

#[must_use]pub fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]pub fn le(&self, other: &Rhs) -> bool

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

#[must_use]pub fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]pub fn ge(&self, other: &Rhs) -> bool

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

impl StructuralEq for Type

impl StructuralPartialEq for Type

impl TryFrom<i32> for Type

type Error = Error

The type returned in the event of a conversion error.

pub fn try_from(i: i32) -> Result<Self, Self::Error>

Performs the conversion.
