Error type reported by numerical integration routines.

Variants

InvalidStencil

The Simpson stencil requires r to be at least two.

Fields

r: usize

Provided number of odd points defining the Simpson stencil.

NonIncreasingBounds

The interval bounds must satisfy a < b.

Fields

a: f64

Lower truncation limit.

b: f64

Upper truncation limit.

NonPositiveInformation

Fisher information must be strictly positive.

Fields

info: f64

Fisher information supplied for the analysis.

NonPositivePreviousInformation

Previous Fisher information must be strictly positive.

Fields

info_prev: f64

Fisher information at the previous analysis.

NonIncreasingInformation

Current Fisher information must exceed the previous analysis value.

Fields

info_prev: f64

Fisher information from the prior analysis.

info: f64

Fisher information proposed for the current analysis.

ShapeMismatch

Stored grid metadata is inconsistent.

Fields

points: usize

Number of Simpson grid points stored.

weights: usize

Number of Simpson weights stored.

values: Option<usize>

Optional number of density values stored.

Trait Implementations

impl Clone for IntegrationError

fn clone(&self) -> IntegrationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IntegrationError

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

Formats the value using the given formatter.

impl Display for IntegrationError

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

Formats the value using the given formatter.

impl Error for IntegrationError

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 IntegrationError

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