The error type for COPP.

Variants

IoError(Error)

Some error occurred in filesystem I/O operations, such as opening/creating log files.

ConstraintError(ConstraintError)

Some error occurred in the Constraint struct, such as invalid input or computation failure.

PathError(PathError)

Some error occurred in the Path struct, such as invalid input or computation failure.

Infeasible(String, String)

The specified optimization problem is reported infeasible by the backend solver.

Unbounded(String, String)

The specified optimization problem is reported unbounded by the backend solver.

InvalidInput(String, String)

The solver/backend rejects the given model or data as invalid input.

InvalidOptions(String, String)

The solver/backend rejects the provided configuration options.

ClarabelSolverError(String, SolverError)

The Clarabel solver returned a concrete internal solver error.

ClarabelSolverStatus(String, SolverStatus)

The Clarabel solver terminated with a non-success status.

Other(String, String)

A backend-specific or uncategorized runtime error is reported.

Trait Implementations

impl Debug for CoppError

Force the debug format of ToppError to be the same as the display format, which is more concise and user-friendly.

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

Formats the value using the given formatter.

impl Display for CoppError

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

Formats the value using the given formatter.

impl Error for CoppError

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<ConstraintError> for CoppError

fn from(source: ConstraintError) -> Self

Converts to this type from the input type.

impl From<Error> for CoppError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<PathError> for CoppError

fn from(source: PathError) -> Self

Converts to this type from the input type.
