Enum ExtractorError 

pub enum ExtractorError {
    InsufficientDocuments(usize),
    VocabularyEmpty,
    InvalidConfiguration(String),
    ModelNotFitted,
    TopicOutOfRange(usize),
    DocumentNotFound(String),
}

Errors that can be returned by TopicModelExtractor.

Variants

InsufficientDocuments(usize)

The corpus has fewer documents than can support topic modelling.

VocabularyEmpty

The vocabulary is empty after filtering.

InvalidConfiguration(String)

A configuration parameter is invalid.

ModelNotFitted

The model has not been fitted yet.

TopicOutOfRange(usize)

An unknown topic id was requested.

DocumentNotFound(String)

An unknown document id was requested.

Trait Implementations

impl Clone for ExtractorError

fn clone(&self) -> ExtractorError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExtractorError

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

Formats the value using the given formatter.

impl Display for ExtractorError

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

Formats the value using the given formatter.

impl Error for ExtractorError

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 ExtractorError

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