Errors that can occur during Tukey test operations.

Variants

TooFewGroups

Fewer than 2 groups were provided.

TooManyGroups(usize)

More groups than the lookup table supports (max 10).

EmptyGroup(usize)

A group contained no observations.

InsufficientDf

Not enough degrees of freedom (need at least 1).

UnsupportedAlpha(f64)

Alpha level not supported — use 0.05 or 0.01.

ZeroVariance

Within-group variance is zero (all observations identical).

GroupTooSmall(usize)

A group needs at least 2 observations (for per-group variance).

ControlGroupOutOfRange(usize)

Control group index is out of range.

TooManyTreatments(usize)

Too many treatment groups for the Dunnett table (max 9).

IoError(String)

I/O error when reading data.

ParseError

Failed to parse a value in CSV data.

Fields

line: usize

column: usize

value: String

EmptyCsv

CSV data has no columns.

Trait Implementations

impl Clone for TukeyError

fn clone(&self) -> TukeyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TukeyError

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

Formats the value using the given formatter.

impl Display for TukeyError

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

Formats the value using the given formatter.

impl Error for TukeyError

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 PartialEq for TukeyError

fn eq(&self, other: &TukeyError) -> 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.
