Enum ScoringError 

pub enum ScoringError {
    ShapeMismatch {
        input: Vec<usize>,
        weights: Vec<usize>,
    },
    AxisOutOfRange {
        axis: usize,
        ndim: usize,
    },
    ZeroWeightSum,
    InvalidProbability {
        value: f64,
    },
    EmptyInput,
}

Error type for scoring operations.

Variants

ShapeMismatch

Input and weights have incompatible shapes.

Fields

input: Vec<usize>

Shape of the input tensor.

weights: Vec<usize>

Shape of the weights tensor.

AxisOutOfRange

Requested axis is out of bounds for the tensor.

Fields

axis: usize

Requested axis.

ndim: usize

Number of dimensions in the tensor.

ZeroWeightSum

All weights sum to zero, cannot normalize.

InvalidProbability

A probability value outside [0, 1] was provided.

Fields

value: f64

The offending value.

EmptyInput

Reduction attempted on an empty tensor.

Trait Implementations

impl Debug for ScoringError

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

Formats the value using the given formatter.

impl Display for ScoringError

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

Formats the value using the given formatter.

impl Error for ScoringError

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.
