The error type for operations in Gurobi Rust API

Variants

FromAPI(String, i32)

An error returned from Gurobi C API. Contains the message and the error code.

NulError(NulError)

Conversion to a C-style null-termined string failed. Contains the underlying std::ffi::NulError.

ModelObjectRemoved

Query/modifying a removed variable or constraint

ModelObjectPending

Model object hasn’t been updated yet. A call to Model::update is needed.

ModelObjectMismatch

Model object comes from a different model

ModelUpdateNeeded

A call to Model::update is required before this operation

AlgebraicError(String)

Modelling errors caused by the user, usually by providing quadratic expressions to methods that expect linear terms such as Model::add_constr.

NotYetSupported(String)

Gurobi feature not yet supported by this crate. Currently for internal use only.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Error> for Error

fn from(err: Error) -> Error

Converts to this type from the input type.

impl From<NulError> for Error

fn from(err: NulError) -> Error

Converts to this type from the input type.

impl PartialEq for Error

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

impl Eq for Error
