Struct parquet::format::Type

pub struct Type(pub i32);

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.

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Type

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

Formats the value using the given formatter.

impl From<&Type> for i32

fn from(e: &Type) -> i32

Converts to this type from the input type.

impl From<&i32> for Type

fn from(i: &i32) -> Self

Converts to this type from the input type.

impl From<Type> for Type

fn from(value: Type) -> Self

Converts to this type from the input type.

impl From<Type> for i32

fn from(e: Type) -> i32

Converts to this type from the input type.

impl From<i32> for Type

fn from(i: i32) -> Self

Converts to this type from the input type.

impl Hash for Type

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 Type

fn cmp(&self, other: &Type) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Type

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

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

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

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

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

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

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

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

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

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 TSerializable for Type

fn write_to_out_protocol<T: TOutputProtocol>( &self, o_prot: &mut T ) -> Result<()>

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

impl TryFrom<Type> for Type

type Error = ParquetError

The type returned in the event of a conversion error.

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

Performs the conversion.

impl Copy for Type

impl Eq for Type

impl StructuralPartialEq for Type
