Failure while validating, fitting, scoring, or serializing a Markov model.

Variants

EmptyCorpus

The corpus contained no sequences.

EmptySequence

One sequence contained no state.

Fields

index: usize

Zero-based sequence position.

NoTransitions

The requested partition contained no adjacent state pair.

Fields

partition: &'static str

Stable partition name.

InvalidHoldout

The holdout would leave no training sequence.

Fields

sequences: usize

Total sequence count.

held_out: usize

Requested held-out count.

InvalidPolicy

Policy or provenance was incomplete or numerically invalid.

Fields

field: &'static str

Invalid field.

reason: &'static str

Concrete requirement.

UnknownState

A scored state was outside the fitted finite vocabulary.

Fields

sequence: usize

Zero-based sequence position.

position: usize

Zero-based state position.

CountOverflow

A transition count exceeded u64.

DuplicateStateLabel

Two distinct states were given the same stable serialization label.

Trait Implementations

impl Clone for MarkovError

fn clone(&self) -> MarkovError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MarkovError

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

Formats the value using the given formatter.

impl Display for MarkovError

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

Formats the value using the given formatter.

impl Eq for MarkovError

impl Error for MarkovError

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 MarkovError

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

Equality operator ==.

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

Inequality operator !=.
