Enum PortfolioError 

pub enum PortfolioError {
    DimensionMismatch(String),
    InvalidArgument(String),
    NotPositiveDefinite(String),
    OptimisationFailed(String),
    Infeasible(String),
    Singular(String),
}

Crate-wide error type. Most fallible operations return PortfolioError rather than panicking so callers can decide how to recover from misconfigured inputs (mismatched shapes, infeasible optimisation, etc.).

Variants

DimensionMismatch(String)

InvalidArgument(String)

NotPositiveDefinite(String)

OptimisationFailed(String)

Infeasible(String)

Singular(String)

Trait Implementations

impl Debug for PortfolioError

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

Formats the value using the given formatter.

impl Display for PortfolioError

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

Formats the value using the given formatter.

impl Error for PortfolioError

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>)
