Errors that can occur during PICARD computation.

Variants

NotConverged

Algorithm did not converge within the maximum number of iterations.

Fields

gradient_norm: f64

Final gradient norm achieved.

tolerance: f64

Requested tolerance.

iterations: usize

Number of iterations performed.

InvalidDimensions

Input dimensions are invalid.

Fields

message: String

Description of the dimension error.

SingularMatrix

A singular matrix was encountered during computation.

ComputationError

General computation error.

Fields

message: String

Description of what went wrong.

InvalidConfig

Invalid configuration parameter.

Fields

parameter: String

Name of the invalid parameter.

message: String

Description of why it’s invalid.

Trait Implementations

impl Clone for PicardError

fn clone(&self) -> PicardError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PicardError

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

Formats the value using the given formatter.

impl Display for PicardError

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

Formats the value using the given formatter.

impl Error for PicardError

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.
