An index construction failure.

Variants

CursorSlotMissing

The weighted cursor scheduler referenced an absent cursor slot.

Fields

slot: usize

Invalid scheduler slot.

LiveFrequencyCache

Exact live-frequency memoization refused inconsistent state or a poisoned lock. No cache failure is interpreted as a zero frequency.

Fields

reason: &'static str

Failed cache invariant or synchronization boundary.

Postings(PostingsError)

A posting list rejected an append.

Stats(Bm25Error)

The corpus had no documents or no tokens.

RowsNotAscending

Documents were added out of row order.

Fields

row: u32

The offending row.

LiveRowOutOfRange

A live-row counter named a row outside its lexical segment.

Fields

segment: usize

Lexical segment ordinal.

row: u32

Invalid row identifier.

row_count: u32

Dense row count of the segment.

LiveLengthMissing

A sealed segment’s dense length counter omitted a valid live row.

Fields

segment: usize

Lexical segment ordinal.

row: u32

Live row without a length counter.

ReplacedRowOutOfRange

A replacement named a row the segment does not hold.

Fields

row: u32

Invalid row identifier.

row_count: u32

Dense row count of the segment.

ReplacedPostingMissing

A replaced row’s previous document names a term the row has no posting for, so the index was not built from that document.

Fields

row: u32

The replaced row.

Trait Implementations

impl Clone for IndexError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexError

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

Formats the value using the given formatter.

impl Display for IndexError

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

Formats the value using the given formatter.

impl Eq for IndexError

impl Error for IndexError

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<Bm25Error> for IndexError

fn from(error: Bm25Error) -> Self

Converts to this type from the input type.

impl From<IndexError> for LexicalFilterError

fn from(error: IndexError) -> Self

Converts to this type from the input type.

impl From<PostingsError> for IndexError

fn from(error: PostingsError) -> Self
