The error type used by this crate.

Variants

ConfigurationMissesLearningStage

The configuration has no or not enough stages in the learning phase. The stages in the learning phase are defined by Configuration::learning_phase_stage_delay_seconds.

ReviewingPhaseEaseFactorEasyUpdateLowerThanOne

The value of Configuration::reviewing_phase_ease_factor_easy_update is lower than one.

ReviewingPhaseEaseFactorHardUpdateGreaterThanOne

The value of Configuration::reviewing_phase_ease_factor_hard_update is greater than one.

ReviewingPhaseInitialEaseFactorLowerThanOne

The value of Configuration::reviewing_phase_initial_ease_factor is lower than one.

Overflow

An overflow occurred.

IllegalJitterStandardDeviation

The standard deviation given for the gaussian jitter variant is not accepted by rand_distr::Normal.

UnknownRandDistrError

An unexpected error in rand_distr occurred.

NegativeRepetitionInterval

An item was repeated before its previous repetition.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl PartialEq for Error

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