Enum SolveError 

pub enum SolveError {
    NoObjective,
    InvalidModel(String),
    NumericalFailure(String),
    InternalSolverError(String),
    Unsupported(String),
    Other(String),
}

Represents the various errors that can occur during modeling or solving an optimization problem.

This type is used by solvers and the modeling API to communicate problems such as missing objectives, invalid models, or numerical issues.

Variants

NoObjective

The model has no objective function defined.

InvalidModel(String)

The model is invalid (e.g., constraints are inconsistent or malformed).

NumericalFailure(String)

A numerical failure occurred during solving (e.g., singular matrix).

InternalSolverError(String)

Internal solver error (unexpected state or panic inside the solver).

Unsupported(String)

The solver does not support a required feature (e.g., non-linear constraints).

Other(String)

Trait Implementations

impl Debug for SolveError

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

Formats the value using the given formatter.

impl Display for SolveError

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

Formats the value using the given formatter.

impl PartialEq for SolveError

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