Enum ProductError 

pub enum ProductError {
    NotRationalTerm(String),
    Factorization,
    NonLinearFactor,
    BoundSubstitution(String),
}

Errors raised by discrete product evaluation.

Variants

NotRationalTerm(String)

Term is not a supported rational function of the index.

Factorization

ℤ-factorisation failed.

NonLinearFactor

An irreducible ℤ-factor has degree > 1.

BoundSubstitution(String)

Bound substitution failed (mirrors summation).

Trait Implementations

impl AlkahestError for ProductError

fn code(&self) -> &'static str

Stable diagnostic code, e.g. "E-DIFF-001".

fn remediation(&self) -> Option<&'static str>

Optional human-readable fix suggestion.

fn span(&self) -> Option<(usize, usize)>

Optional source span (start_byte, end_byte) within the input text.

impl Clone for ProductError

fn clone(&self) -> ProductError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProductError

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

Formats the value using the given formatter.

impl Display for ProductError

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

Formats the value using the given formatter.

impl Error for ProductError

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 ProductError

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