Helper to build cursors over ObjectStores

Implementations§

Source§

impl<Err> CursorBuilder<Err>

Source

pub fn open(self) -> impl Future<Output = Result<Cursor<Err>, Err>>

Open the cursor

Internally, this uses IDBObjectStore::openCursor.

Source

pub fn open_key(self) -> impl Future<Output = Result<Cursor<Err>, Err>>

Open the cursor as a key-only cursor

Internally, this uses IDBObjectStore::openKeyCursor.

Source

pub fn range(self, range: impl RangeBounds<JsValue>) -> Result<Self, Err>

Limit the range of the cursor

Internally, this sets this property.

Source

pub fn direction(self, direction: CursorDirection) -> Self

Define the direction of the cursor

Internally, this sets this property.
