Errors returned by datarust operations.

Every fallible public API returns Result<T, DatarustError>. The variant describes which class of problem occurred.

Variants

NotFitted(String)

A transformer was used before being fitted.

InvalidInput(String)

The supplied data is malformed or otherwise invalid for the operation.

ShapeMismatch

Two operands did not have compatible dimensions.

Fields

expected: String

A description of what was expected.

actual: String

A description of what was actually provided.

EmptyInput(String)

An empty collection was provided where at least one element is required.

AllMissing(String)

A column (or set of columns) consisted entirely of missing values.

UnknownCategory(String)

A category unseen at fit time was encountered at transform time.

UnknownLabel(String)

A label unseen at fit time was encountered at transform time.

InvalidConfig(String)

A transformer was constructed with an illegal parameter combination.

Singular(String)

A numerical operation broke down (e.g. division by zero, singular matrix).

Io(Error)

An IO failure while reading from or writing to disk.

Serde(Error)

A (de)serialization failure (e.g. malformed JSON).

Trait Implementations

impl Debug for DatarustError

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

Formats the value using the given formatter.

impl Display for DatarustError

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

Formats the value using the given formatter.

impl Error for DatarustError

fn source(&self) -> Option<&(dyn StdError + '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.
