Struct xsd_types::value::Decimal

pub struct Decimal { /* private fields */ }

Decimal number.

Internally a decimal number is represented as a BigRational with a finite decimal representation.

Implementations

impl Decimal

pub unsafe fn new_unchecked(r: BigRational) -> Self

Creates a new decimal number from a rational number.

Safety

The input rational number must have a finite decimal representation.

pub fn zero() -> Self

pub fn is_zero(&self) -> bool

pub fn is_positive(&self) -> bool

pub fn is_negative(&self) -> bool

pub fn decimal_type(&self) -> Option<DecimalDatatype>

pub fn lexical_representation(&self) -> &DecimalBuf

Trait Implementations

fn from(value: BigInt) -> Self

Converts to this type from the input type.

impl From<Decimal> for BigRational

fn from(value: Decimal) -> Self

Converts to this type from the input type.

impl From<DecimalBuf> for Decimal

fn from(value: DecimalBuf) -> Self

Converts to this type from the input type.

impl From<Integer> for Decimal

impl FromStr for Decimal

type Err = InvalidDecimal

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Decimal

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 Decimal

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

impl PartialEq<Decimal> for Decimal

fn eq(&self, other: &Self) -> 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.

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