Enum ScaleDesignError 

pub enum ScaleDesignError {
    InvalidWeights {
        reason: String,
    },
    IncompatibleDimensions {
        reason: String,
    },
    NonFiniteInput {
        reason: String,

    RowMaterializationFailed {

    SvdFailed {
        reason: String,
    },
}

Typed error variants for the scale-deviation design module.

External-facing helpers continue to return Result<_, String>; this enum is materialized internally and converted at the boundary so that error text remains byte-identical to the previous format! output.

Variants

InvalidWeights

Weight vector contains an invalid entry (NaN/inf, negative, or sums to a non-positive / non-finite total).

Fields

reason: String

IncompatibleDimensions

Dimensions of the supplied matrices/vectors are inconsistent.

Fields

reason: String

NonFiniteInput

Input value is not finite where finiteness is required (e.g. saved projection cutoff alpha).

Fields

reason: String

DegenerateDesign

Saved payload is partially populated or the projection is degenerate (e.g. zero rows with non-empty columns).

Fields

reason: String

RowMaterializationFailed

Row materialization from an underlying DesignMatrix failed.

Fields

reason: String

SvdFailed

Thin SVD of the weighted primary design failed or produced no singular vectors.

Fields

reason: String

Trait Implementations

impl Clone for ScaleDesignError

fn clone(&self) -> ScaleDesignError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ScaleDesignError

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

Formats the value using the given formatter.

impl Display for ScaleDesignError

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

Formats the value using the given formatter.

impl Error for ScaleDesignError

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.
