Enum DecimalType 

#[repr(u8)]
pub enum DecimalType {
    I8 = 0,
    I16 = 1,
    I32 = 2,
    I64 = 3,
    I128 = 4,
    I256 = 5,
}

Type of the decimal values.

This is used for other crates to understand the different underlying representations possible for decimals.

Variants

I8 = 0

8-bit decimal value type.

I16 = 1

16-bit decimal value type.

I32 = 2

32-bit decimal value type.

I64 = 3

64-bit decimal value type.

I128 = 4

128-bit decimal value type.

I256 = 5

256-bit decimal value type.

Implementations

impl DecimalType

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of DecimalType.

pub fn from_i32(value: i32) -> Option<DecimalType>

👎Deprecated: Use the TryFrom<i32> implementation instead

Converts an i32 to a DecimalType, or None if value is not a valid variant.

impl DecimalType

pub fn smallest_decimal_value_type(decimal_dtype: &DecimalDType) -> DecimalType

Maps a DecimalDType (precision) into the smallest DecimalType that can represent it.

pub fn byte_width(&self) -> usize

Returns the size in bytes of the underlying native type for this decimal type.

pub fn is_compatible_decimal_value_type(self, dtype: DecimalDType) -> bool

True if Self can represent every value of the type DecimalDType.

Trait Implementations

impl Clone for DecimalType

fn clone(&self) -> DecimalType

Returns a duplicate 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 Default for DecimalType

fn default() -> DecimalType

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DecimalType

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DecimalType

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

Formats the value using the given formatter.

impl From<DecimalType> for i32

fn from(value: DecimalType) -> i32

Converts to this type from the input type.

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,

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 Serialize for DecimalType

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<PType> for DecimalType

type Error = VortexError

The type returned in the event of a conversion error.

fn try_from(value: PType) -> Result<Self, Self::Error>

Performs the conversion.
