Enum NonNormalCapabilityError 

pub enum NonNormalCapabilityError {
    NonPositiveData,
    InsufficientData,
    SpecTransformError,
    CapabilityError,
    NoSpecLimits,
}

Errors that can arise from non-normal process capability analysis.

Variants

NonPositiveData

All data values must be strictly positive for Box-Cox transformation.

InsufficientData

At least 4 data points are required for reliable capability analysis.

SpecTransformError

Failed to transform a specification limit (e.g., limit is not positive).

CapabilityError

Capability computation failed (e.g., all transformed data are identical).

NoSpecLimits

At least one specification limit (USL or LSL) must be provided.

Trait Implementations

impl Clone for NonNormalCapabilityError

fn clone(&self) -> NonNormalCapabilityError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NonNormalCapabilityError

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

Formats the value using the given formatter.

impl Display for NonNormalCapabilityError

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

Formats the value using the given formatter.

impl Error for NonNormalCapabilityError

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<TransformError> for NonNormalCapabilityError

fn from(e: TransformError) -> Self

Converts to this type from the input type.

impl PartialEq for NonNormalCapabilityError

fn eq(&self, other: &NonNormalCapabilityError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
