An error from a core model: a table that can’t be built, a lookup it refuses, or an input outside a model’s domain.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TableTooShort

A table needs at least min knots.

Fields

min: usize

The minimum number of knots.

got: usize

The number supplied.

TableLengthMismatch

The abscissa and ordinate columns have different lengths.

Fields

xs: usize

Number of abscissae.

ys: usize

Number of ordinates.

TableNotFinite

A table value is NaN or infinite.

Fields

index: usize

Index of the offending knot.

TableNotIncreasing

Abscissae must strictly increase.

Fields

index: usize

Index of the first abscissa that is not greater than its predecessor.

OutOfRange

A lookup outside the table, on a table whose policy is crate::interp::Extrapolation::Error.

Fields

x: f64

The requested abscissa.

min: f64

The first abscissa.

max: f64

The last abscissa.

TableOverflow

An interval’s width, its secant slope or a spline slope overflows f64.

Fields

interval: usize

Index of the interval [x_i, x_{i+1}].

ExtrapolationOverflow

Linear extrapolation gave a value that is not finite.

Fields

x: f64

The requested abscissa.

NanLookup

A lookup at NaN.

InvalidRandomState

A serialized random generator state that is not four 0x-prefixed hexadecimal 64-bit words, or is all zero.

QuadratureNotFinite

An integrand returned NaN or an infinity.

Fields

x: f64

Where the integrand was evaluated.

QuadratureDidNotConverge

Adaptive integration didn’t meet its tolerance within its subinterval budget.

Fields

component: usize

The component furthest from its tolerance.

value: f64

Its best estimate.

error: f64

Its error estimate.

intervals: usize

The subintervals used.

Domain

An input outside a model’s domain, such as a latitude beyond ±90°.

Fields

what: &'static str

What the value is.

value: f64

The offending value.

Trait Implementations

impl Clone for CoreError

fn clone(&self) -> CoreError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CoreError

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

Formats the value using the given formatter.

impl Display for CoreError

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

Formats the value using the given formatter.

impl Error for CoreError

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 CoreError

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