Enum WeightViolation 

pub enum WeightViolation {
    NonFiniteWeight {
        index: usize,
    },
    NegativeWeight {
        index: usize,
        weight: f64,
    },
    GrossExposureExceeded {
        gross: f64,
        cap: f64,
    },
}

A specific way a weight vector violates the policy.

Variants

NonFiniteWeight

A weight is NaN or infinite — an abusive/garbage vector.

Fields

index: usize

NegativeWeight

A negative weight while shorts are disallowed.

Fields

index: usize

weight: f64

GrossExposureExceeded

Gross exposure exceeded the leverage cap.

Fields

gross: f64

cap: f64

Trait Implementations

impl Clone for WeightViolation

fn clone(&self) -> WeightViolation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WeightViolation

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

Formats the value using the given formatter.

impl PartialEq for WeightViolation

fn eq(&self, other: &WeightViolation) -> 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 Serialize for WeightViolation

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
