Enum PortfolioWeightError 

pub enum PortfolioWeightError {
    NonFiniteWeight,
    EmptyAssetId,
    DuplicateAssetId(String),
    NonFiniteTolerance,
    NegativeTolerance,
}

Errors returned by portfolio weight helpers.

Variants

NonFiniteWeight

Weight values must be finite.

EmptyAssetId

Asset identifiers must be non-empty after trimming whitespace.

DuplicateAssetId(String)

Asset identifiers must be unique in a weight set.

NonFiniteTolerance

Tolerances must be finite.

NegativeTolerance

Tolerances must not be negative.

Trait Implementations

impl Clone for PortfolioWeightError

fn clone(&self) -> PortfolioWeightError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PortfolioWeightError

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

Formats the value using the given formatter.

impl Display for PortfolioWeightError

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

Formats the value using the given formatter.

impl Error for PortfolioWeightError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for PortfolioWeightError

fn eq(&self, other: &PortfolioWeightError) -> 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.
