Struct parquet_format::DecimalType

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

Decimal logical type annotation

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, and BINARY

Fields

scale: i32

precision: i32

Implementations

impl DecimalType

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

pub fn read_from_in_protocol(
    i_prot: &mut dyn TInputProtocol
) -> Result<DecimalType>

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

Trait Implementations

impl Clone for DecimalType

pub fn clone(&self) -> DecimalType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DecimalType

impl Ord for DecimalType

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

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

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

pub fn ne(&self, other: &DecimalType) -> bool

This method tests for !=.

impl PartialOrd<DecimalType> for DecimalType

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

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

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

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

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

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

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

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

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

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