Errors from forecast operations.

Variants

InsufficientData

The input time-series has fewer observations than the model requires.

Fields

min: usize

Minimum number of data points required.

got: usize

Number of data points actually provided.

InvalidInput(String)

A user-supplied parameter or input is invalid.

ConvergenceFailed

The optimiser did not converge within the iteration limit.

Fields

iterations: usize

Number of iterations completed before giving up.

InvalidParams

A model hyper-parameter has an invalid value.

Fields

name: &'static str

Name of the invalid parameter.

value: String

The invalid value that was supplied.

reason: &'static str

Human-readable explanation of why the value is rejected.

NumericalInstability(String)

A computation produced NaN / Inf or similar numeric failure.

NotFitted

The model has not been fitted yet.

Compute(ComputeError)

An error forwarded from the compute engine.

Trait Implementations

impl Debug for ForecastError

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

Formats the value using the given formatter.

impl Display for ForecastError

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

Formats the value using the given formatter.

impl Error for ForecastError

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.

impl From<ForecastError> for AnalyticsError

fn from(source: ForecastError) -> Self

Converts to this type from the input type.
