Struct Price 

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

Domain value type representing a price.

Implementations

impl Price

pub const ZERO: Self

Zero price value.

pub const fn new(value: u128) -> Self

Creates a new price from a raw integer value.

pub fn try_new(value: u128) -> Result<Self, PriceLevelError>

Creates a validated price from a raw integer value.

Errors

Returns PriceLevelError::InvalidFieldValue if value ever fails the price invariant. Every u128 is currently a valid price, so this constructor is presently infallible; the Result is part of its stable contract so validation can be tightened without a breaking change.

pub fn from_f64(value: f64) -> Result<Self, PriceLevelError>

Creates a price from an f64 value (rounded to the nearest integer).

Errors

Returns PriceLevelError::InvalidOperation if value is not finite (NaN or infinite), is negative, or (after rounding) does not fit in a u128. The range check is explicit because an f64-to-u128 as cast saturates rather than failing, which would silently clamp out-of-range input to u128::MAX.

pub fn to_f64_lossy(self) -> f64

Converts the price to f64 with potential precision loss.

pub const fn as_u128(self) -> u128

Returns the inner raw value.

Trait Implementations

impl Clone for Price

fn clone(&self) -> Price

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Price

impl Debug for Price

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

Formats the value using the given formatter.

impl Default for Price

fn default() -> Price

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Price

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Price

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

Formats the value using the given formatter.

impl Eq for Price

impl FromStr for Price

type Err = PriceLevelError

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 Price

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 Price

fn cmp(&self, other: &Price) -> 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 Price

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

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
