Struct parquet2::schema::types::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, Error>

pub async fn stream_from_in_protocol(
    i_prot: &'_ mut (dyn TInputStreamProtocol + '_)
) -> Result<DecimalType, Error>

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

pub async fn write_to_out_stream_protocol(
    &'_ self,
    o_prot: &'_ mut (dyn TOutputStreamProtocol + '_)
) -> Result<usize, Error>

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<(), Error>

impl Hash for DecimalType

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

Feeds this value into the given Hasher.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<DecimalType> for DecimalType

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

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

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

This method tests for !=.

impl PartialOrd<DecimalType> 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

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
