HNSW index operation errors

These errors occur during HNSW index operations such as insertion, search, and index maintenance.

Error Variants

• VectorDimensionMismatch - Vector length doesn’t match configured dimension
• DuplicateVectorId - Attempting to insert a vector with existing ID
• VectorNotFound - No vector found with specified ID
• IndexNotInitialized - Operation attempted on uninitialized index
• IndexCorrupted - Index structure is corrupted or invalid

Examples

use sqlitegraph::hnsw::errors::HnswIndexError;

match error {
    HnswIndexError::VectorDimensionMismatch { expected, actual } => {
        println!("Expected {} dimensions, got {}", expected, actual);
    }
    HnswIndexError::DuplicateVectorId(id) => {
        println!("Vector ID {} already exists", id);
    }
    // Handle other error types...
}

Variants

Index structure corruption detected

CapacityExceeded

Index capacity exceeded

InvalidSearchParameters

Trait Implementations

impl Clone for HnswIndexError

fn clone(&self) -> HnswIndexError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HnswIndexError

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

Formats the value using the given formatter.

impl Display for HnswIndexError

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

Formats the value using the given formatter.

impl Error for HnswIndexError

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<HnswIndexError> for HnswError

fn from(err: HnswIndexError) -> Self

Converts to this type from the input type.

impl PartialEq for HnswIndexError

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