Struct FixedPrice 

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

Fixed-point price representation. 1 tick = 0.0001 (scale factor 10,000). Eliminates f64 comparison issues (no PRICE_EPSILON), enables Ord (no NaN), and uses integer arithmetic (1-5ns vs 20-100ns for f64 ops).

Serializes as f64 on the wire for JSON backward compatibility.

Implementations

impl FixedPrice

pub const SCALE: u64 = 10_000

pub const ZERO: Self

pub const ONE: Self

pub fn from_f64(price: f64) -> Self

pub fn to_f64(self) -> f64

pub fn raw(self) -> u64

pub fn from_raw(raw: u64) -> Self

pub fn complement(self) -> Self

1.0 - self, exact in fixed-point. Used for NO-side price inversion.

pub fn midpoint(self, other: Self) -> Self

Trait Implementations

impl Clone for FixedPrice

fn clone(&self) -> FixedPrice

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FixedPrice

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

Formats the value using the given formatter.

impl Default for FixedPrice

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FixedPrice

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

Deserialize this value from the given Serde deserializer.

impl Display for FixedPrice

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

Formats the value using the given formatter.

impl From<FixedPrice> for f64

fn from(v: FixedPrice) -> Self

Converts to this type from the input type.

impl From<f64> for FixedPrice

fn from(v: f64) -> Self

Converts to this type from the input type.

impl Hash for FixedPrice

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 FixedPrice

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

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

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

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

Serialize this value into the given Serde serializer.

impl Copy for FixedPrice

impl Eq for FixedPrice
