Struct VectorTable 

pub struct VectorTable<'vtab> { /* private fields */ }

The virtual table implementation for vector search.

db is a raw pointer to the VTabConnection that SQLite provides to connect/create. SQLite guarantees the connection outlives the virtual table, so this pointer is valid for the entire lifetime of VectorTable.

Trait Implementations

impl<'vtab> CreateVTab<'vtab> for VectorTable<'vtab>

const SHADOW_NAMES: &'static [&'static str]

List of shadow table names.

fn create( db: &'vtab VTabConnection, aux: &'vtab Self::Aux, args: &[&str], ) -> Result<(String, Self)>

Corresponds to xCreate.

fn destroy(self) -> DisconnectResult<Self>

Corresponds to xDestroy, when DROP TABLE is run on the virtual table. The virtual table implementation should destroy any underlying state that was created by Self::create.

impl<'vtab> FindFunctionVTab<'vtab> for VectorTable<'vtab>

fn functions(&'vtab self) -> &'vtab VTabFunctionList<'vtab, Self>

Retrieve a reference to the VTabFunctionList associated with this virtual table.

impl<'vtab> TransactionVTab<'vtab> for VectorTable<'vtab>

type Transaction = VectorTransaction

fn begin(&'vtab self) -> Result<Self::Transaction>

Begin a transaction.

impl<'vtab> UpdateVTab<'vtab> for VectorTable<'vtab>

fn update(&'vtab self, info: &mut ChangeInfo) -> Result<i64>

Modify a single row in the virtual table. The info parameter may be used to determine the type of change being performed by this update.

impl<'vtab> VTab<'vtab> for VectorTable<'vtab>

type Aux = ()

Additional data associated with the virtual table module.

type Cursor = VectorCursor

Cursor implementation for this virtual table.

fn connect( db: &'vtab VTabConnection, _aux: &'vtab Self::Aux, args: &[&str], ) -> Result<(String, Self)>

Corresponds to xConnect.

fn best_index(&'vtab self, info: &mut IndexInfo) -> Result<()>

Corrresponds to xBestIndex.

fn open(&'vtab self) -> Result<Self::Cursor>

Create an uninitialized query.

fn disconnect(self) -> Result<(), (Self, Error)>

Corresponds to xDisconnect. This method is called when the database connection is being closed. The implementation should not remove the underlying data, but it should release any resources associated with the virtual table implementation. This method is the inverse of Self::connect.
