Errors from compute operations.

Variants

DimensionMismatch

Input slices have incompatible lengths.

Fields

expected: usize

Expected dimension.

got: usize

Actual dimension received.

SingularMatrix

Matrix is singular and cannot be inverted/solved.

InsufficientData

Insufficient data for the requested operation.

Fields

min: usize

Minimum number of points required.

got: usize

Actual number of points provided.

InvalidParameter

Invalid parameter value.

Fields

name: &'static str

Parameter name.

value: String

Supplied value.

reason: &'static str

Why the value is invalid.

NumericalInstability(String)

Numerical instability detected.

Internal(String)

Internal error (e.g. thread pool, system resource failure).

Trait Implementations

impl Debug for ComputeError

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

Formats the value using the given formatter.

impl Display for ComputeError

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

Formats the value using the given formatter.

impl Error for ComputeError

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<ComputeError> for ForecastError

fn from(source: ComputeError) -> Self

Converts to this type from the input type.
