Re-exported validation utilities.

This includes validators for data integrity, parameter constraints, and common model hyperparameter validation. Errors that can occur during validation.

Each variant provides detailed information about the specific validation failure, including parameter names, expected constraints, and actual values.

Variants

ValidationFailed(String)

General validation failure with a descriptive message.

InvalidParameter

Parameter value is outside the allowed range.

Fields

name: String

Name of the parameter that failed validation.

value: f64

Actual value provided.

constraint: String

Expected constraint or range.

DimensionMismatch

Array dimensions don’t match expected values.

Fields

expected: String

Expected dimension or size.

actual: String

Actual dimension or size found.

EmptyData

Input data is empty.

NonFiniteValue

Non-finite value (NaN, Inf, -Inf) found in data.

InvalidProbability

Probability value is outside [0, 1] range. The invalid probability value.

Fields

value: f64

Trait Implementations

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl Error for ValidationError

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<ValidationError> for GBRTError

fn from(source: ValidationError) -> Self

Converts to this type from the input type.
