A matrix, sensitivity, or dataset failure.

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.

Core(Error)

A failure from the balanced model, its readers, or its writers.

Io(Error)

An underlying I/O failure reading or writing a file.

Routed through the hub’s variant so the message a caller sees is the same one every other powerio surface prints for the same failure.

DimensionMismatch

Fields

n: usize

b_len: usize

ShapeMismatch

Fields

what: &'static str

expected: usize

got: usize

SingularNetwork

InvalidSensitivityOptions

Fields

reason: String

SensitivitySolveDidNotConverge

Fields

iterations: usize

relative_residual: f64

Mtx(String)

Parquet(String)

EmptyScenarioBatch

ScenarioIdOverflow

Fields

base: i64

index: usize

0-based position of the snapshot whose base + index overflowed.

NormalizedGridfmSnapshot

Fields

scenario: i64

NonFiniteGridfmValue

Fields

scenario: i64

element: &'static str

ScenarioShapeMismatch

Fields

index: usize

0-based position of the offending snapshot in the batch (independent of the snapshot’s scenario id).

reason: ScenarioMismatch

Implementations

impl Error

pub fn category(&self) -> ErrorCategory

Classify this error, using the hub’s taxonomy.

The match is exhaustive over the variant set, so a new variant must be classified here before it compiles.

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, __formatter: &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(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
