Struct Index 

pub struct Index { /* private fields */ }

Lookup and cursor access through one secondary index.

Implementations

impl Index

pub async fn get(&mut self, values: &[Value]) -> Result<Record, IndexedDBError>

Loads the first row that matches values.

pub async fn get_key( &mut self, values: &[Value], ) -> Result<String, IndexedDBError>

Resolves the primary key for the first row that matches values.

pub async fn get_all( &mut self, values: &[Value], range: Option<KeyRange>, ) -> Result<Vec<Record>, IndexedDBError>

Loads every row that matches values and range.

pub async fn get_all_keys( &mut self, values: &[Value], range: Option<KeyRange>, ) -> Result<Vec<String>, IndexedDBError>

Loads every primary key that matches values and range.

pub async fn count( &mut self, values: &[Value], range: Option<KeyRange>, ) -> Result<i64, IndexedDBError>

Counts rows that match values and range.

pub async fn delete(&mut self, values: &[Value]) -> Result<i64, IndexedDBError>

Deletes rows that match values and returns the delete count.

pub async fn delete_range( &mut self, values: &[Value], range: KeyRange, ) -> Result<i64, IndexedDBError>

Deletes rows that match values and range and returns the delete count.

pub async fn open_cursor( &mut self, values: &[Value], range: Option<KeyRange>, direction: CursorDirection, ) -> Result<Cursor, IndexedDBError>

Opens a full-value cursor over the secondary index.

pub async fn open_key_cursor( &mut self, values: &[Value], range: Option<KeyRange>, direction: CursorDirection, ) -> Result<Cursor, IndexedDBError>

Opens a key-only cursor over the secondary index.
