Errors that could occur when running the core Newton-Gauss solve.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotFound(Id)

ID was not found.

WrongNumberGuesses

There should be exactly 1 guess per variable, but you supplied the wrong number.

Fields

labels: usize

How many variables/labels were given.

guesses: usize

How many guesses were given.

MissingGuess

Constraint references a variable that doesn’t appear in the initial guesses.

Fields

constraint_id: usize

Which constraint ID referenced a missing variable.

variable: Id

Which variable was missing.

FaerMatrix

Faer: could not create a matrix.

Fields

error: CreationError

Underlying error.

Faer

Faer: general error.

Fields

error: FaerError

Underlying error.

FaerSolve

Faer: could not solve the matrix in the Newton-Gauss loop.

Fields

error: LuError

Underlying error.

FaerSvd(SvdError)

Faer: could not decompose Jacobian.

DidNotConverge

Solver did not find a solution within the allowed number of iterations. Consider raising the iterations?

EmptySystemNotAllowed

You provided an empty constraint system.

Trait Implementations

impl Debug for NonLinearSystemError

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

Formats the value using the given formatter.

impl Display for NonLinearSystemError

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

Formats the value using the given formatter.

impl Error for NonLinearSystemError

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.
