Struct PositiveDecimal 

pub struct PositiveDecimal(/* private fields */);

Direct access to decimal types. Decimal constrained to x > 0.

Implementations

impl PositiveDecimal

pub fn new(value: BigDecimal) -> Result<PositiveDecimal, DecimalConstraintError>

Builds a positive decimal.

Errors

Returns DecimalConstraintError when value <= 0.

pub const fn as_decimal(&self) -> &BigDecimal

Returns the wrapped decimal by reference.

pub fn into_inner(self) -> BigDecimal

Returns the wrapped decimal.

Trait Implementations

impl AsRef<BigDecimal> for PositiveDecimal

fn as_ref(&self) -> &BigDecimal

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for PositiveDecimal

fn clone(&self) -> PositiveDecimal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PositiveDecimal

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

Formats the value using the given formatter.

impl Decimal128Mantissa for PositiveDecimal

fn try_to_i128_mantissa(&self, target_scale: u32) -> Option<i128>

Returns the mantissa after rescaling to target_scale, or None when the result exceeds decimal128 precision or the active backend cannot represent the conversion.

impl<'de> Deserialize<'de> for PositiveDecimal

fn deserialize<D>( deserializer: D, ) -> Result<PositiveDecimal, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PositiveDecimal

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

Formats the value using the given formatter.

impl Eq for PositiveDecimal

impl From<PositiveDecimal> for BigDecimal

fn from(value: PositiveDecimal) -> BigDecimal

Converts to this type from the input type.

impl From<PositiveDecimal> for NonNegativeDecimal

fn from(value: PositiveDecimal) -> NonNegativeDecimal

Converts to this type from the input type.

impl PartialEq for PositiveDecimal

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

fn partial_cmp(&self, other: &PositiveDecimal) -> 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 PositiveDecimal

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for PositiveDecimal

impl TryFrom<BigDecimal> for PositiveDecimal

type Error = DecimalConstraintError

The type returned in the event of a conversion error.

fn try_from( value: BigDecimal, ) -> Result<PositiveDecimal, <PositiveDecimal as TryFrom<BigDecimal>>::Error>

Performs the conversion.
