Struct KellyFraction 

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

A validated Kelly fraction in the range [0.0, 1.0].

Represents the fraction of available capital to allocate to a trade.

Implementations

impl KellyFraction

pub fn zero() -> Self

The zero fraction — no allocation.

pub fn as_decimal(&self) -> Decimal

The raw fraction value in [0.0, 1.0].

pub fn is_zero(&self) -> bool

Whether this fraction is zero (system has no edge).

Trait Implementations

impl Clone for KellyFraction

fn clone(&self) -> KellyFraction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KellyFraction

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

Formats the value using the given formatter.

impl Display for KellyFraction

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

Formats the value using the given formatter.

impl Ord for KellyFraction

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

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

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