Trait Implementations

impl<const W: u8, const S: u8> AsValue for FixedDecimal<W, S>

fn as_empty_value() -> Value

Return an “empty” (NULL-like) value variant for this type. Used when constructing composite Value containers (arrays, maps) or representing absent optional data. This should never allocate and should not rely on default trait implementations of Self.

fn as_value(self) -> Value

Convert this value into its owned Value representation. This should perform any necessary wrapping (e.g. collections into List, decimals into Decimal) but avoid lossy transformations unless explicitly documented.

fn try_from_value(value: Value) -> Result<FixedDecimal<W, S>, Error>

where FixedDecimal<W, S>: Sized,

Attempt to convert a dynamic Value into Self.

fn parse(input: impl AsRef<str>) -> Result<FixedDecimal<W, S>, Error>

Parse a full string into Self delegating to [AsValue::extract].

impl<const WIDTH: u8, const SCALE: u8> Clone for FixedDecimal<WIDTH, SCALE>

fn clone(&self) -> FixedDecimal<WIDTH, SCALE>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const WIDTH: u8, const SCALE: u8> Debug for FixedDecimal<WIDTH, SCALE>

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

Formats the value using the given formatter.

impl<const WIDTH: u8, const SCALE: u8> Default for FixedDecimal<WIDTH, SCALE>

fn default() -> FixedDecimal<WIDTH, SCALE>

Returns the “default value” for a type.

impl<const W: u8, const S: u8> From<Decimal> for FixedDecimal<W, S>

fn from(value: Decimal) -> FixedDecimal<W, S>

Converts to this type from the input type.

impl<const WIDTH: u8, const SCALE: u8> Hash for FixedDecimal<WIDTH, SCALE>

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<const WIDTH: u8, const SCALE: u8> Ord for FixedDecimal<WIDTH, SCALE>

fn cmp(&self, other: &FixedDecimal<WIDTH, SCALE>) -> 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<const WIDTH: u8, const SCALE: u8> PartialEq for FixedDecimal<WIDTH, SCALE>

fn eq(&self, other: &FixedDecimal<WIDTH, SCALE>) -> 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<const WIDTH: u8, const SCALE: u8> PartialOrd for FixedDecimal<WIDTH, SCALE>

fn partial_cmp(&self, other: &FixedDecimal<WIDTH, SCALE>) -> 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.
