Errors that can occur while configuring or running a chi-squared test.

Variants

InvalidSamples

Zero samples were requested.

Fields

samples: usize

InvalidBins

Fewer than two bins were requested.

Fields

bins: usize

SamplesLessThanBins

Fewer samples than bins were requested (the test would be meaningless).

Fields

samples: usize

bins: usize

InvalidZLimit

A non-positive or non-finite z-limit was supplied.

Fields

z_limit: f64

EmptyCaseName

A test case name was empty or whitespace-only.

DuplicateCaseName

Two cases in the same suite shared a name.

Fields

name: String

NonFiniteSample

The generator produced a non-finite (NaN/inf) value.

Fields

case: String

sample_index: usize

value: f64

OutOfRangeSample

The generator produced a value outside [0, 1).

Fields

case: String

sample_index: usize

value: f64

Trait Implementations

impl Debug for ChiSqError

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

Formats the value using the given formatter.

impl Display for ChiSqError

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

Formats the value using the given formatter.

impl Error for ChiSqError

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<ChiSqError> for SuiteError

fn from(source: ChiSqError) -> Self

Converts to this type from the input type.
