Struct ObjectStore 

pub struct ObjectStore { /* private fields */ }

CRUD, range-query, and cursor access for one object store.

Implementations

impl ObjectStore

pub async fn get(&mut self, id: &str) -> Result<Record, IndexedDBError>

Loads one record by primary key.

pub async fn get_key(&mut self, id: &str) -> Result<String, IndexedDBError>

Resolves the primary key for id.

pub async fn add(&mut self, record: Record) -> Result<(), IndexedDBError>

Inserts a new row and fails if the key already exists.

pub async fn put(&mut self, record: Record) -> Result<(), IndexedDBError>

Upserts a row by primary key.

pub async fn delete(&mut self, id: &str) -> Result<(), IndexedDBError>

Deletes one row by primary key.

pub async fn clear(&mut self) -> Result<(), IndexedDBError>

Deletes every row in the object store.

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

Loads every row that matches range.

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

Loads every primary key that matches range.

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

Counts rows that match range.

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

Deletes rows that match range and returns the delete count.

pub fn index(&self, name: &str) -> Index

Returns a typed handle for one secondary index.

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

Opens a full-value cursor over the object store.

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

Opens a key-only cursor over the object store.
