Struct parquet::format::DecimalType

pub struct DecimalType {
    pub scale: i32,
    pub precision: i32,
}

Decimal logical type annotation

Scale must be zero or a positive integer less than or equal to the precision. Precision must be a non-zero positive integer.

To maintain forward-compatibility in v1, implementations using this logical type must also set scale and precision on the annotated SchemaElement.

Allowed for physical types: INT32, INT64, FIXED_LEN_BYTE_ARRAY, and BYTE_ARRAY.

Fields

scale: i32

precision: i32

Implementations

impl DecimalType

pub fn new(scale: i32, precision: i32) -> DecimalType

Trait Implementations

impl Clone for DecimalType

fn clone(&self) -> DecimalType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DecimalType

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

Formats the value using the given formatter.

impl Hash for DecimalType

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 DecimalType

fn cmp(&self, other: &DecimalType) -> 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 DecimalType

fn eq(&self, other: &DecimalType) -> 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 DecimalType

fn partial_cmp(&self, other: &DecimalType) -> 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.

impl TSerializable for DecimalType

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

Reads the struct from the input Thrift protocol

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

Writes the struct to the output Thrift protocol
