Enum SolverError 

pub enum SolverError {
    NotPolynomial(String),
    HighDegree(usize),
    ShapeMismatch,
}

Errors from the polynomial system solver.

Variants

NotPolynomial(String)

An equation is not a polynomial in the given variables.

HighDegree(usize)

Back-substitution would require solving a degree > 2 univariate — not yet implemented for general algebraic numbers.

ShapeMismatch

Number of equations doesn’t match number of variables (for zero-dim check).

Trait Implementations

impl AlkahestError for SolverError

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 SolverError

fn clone(&self) -> SolverError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SolverError

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

Formats the value using the given formatter.

impl Display for SolverError

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

Formats the value using the given formatter.

impl Error for SolverError

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 From<SolverError> for DiophantineError

fn from(e: SolverError) -> Self

Converts to this type from the input type.
