Enum YieldCurveError 

pub enum YieldCurveError {
    InsufficientData {
        method: &'static str,
        need: usize,
        got: usize,
    },
    InvalidPoint(String),
    FitFailed(String),
    InvalidTimeRange(String),
}

Errors returned by curve construction.

Variants

InsufficientData

Not enough points for the requested method.

Fields

method: &'static str

need: usize

got: usize

InvalidPoint(String)

A point failed validation (NaN/infinite, negative x, duplicate x).

FitFailed(String)

Parametric fit (Nelson-Siegel, Svensson) did not converge or produced implausible parameters.

InvalidTimeRange(String)

Forward-rate computation received t1 >= t2, non-finite times, or produced a non-finite result (e.g. taking a negative discount factor to a fractional power).

Trait Implementations

impl Clone for YieldCurveError

fn clone(&self) -> YieldCurveError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for YieldCurveError

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

Formats the value using the given formatter.

impl Display for YieldCurveError

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

Formats the value using the given formatter.

impl Eq for YieldCurveError

impl Error for YieldCurveError

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 YieldCurveError

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