Implementations

impl Factory

pub fn get() -> Result<Factory>

Retrieve the global Factory from the browser

This internally uses indexedDB.

pub fn cmp(&self, lhs: &JsValue, rhs: &JsValue) -> Result<Ordering>

Compare two keys for ordering

Returns an error if one of the two values would not be a valid IndexedDb key.

This internally uses IDBFactory::cmp.

pub async fn delete_database(&self, name: &str) -> Result<()>

Delete a database

Returns an error if something failed during the deletion. Note that trying to delete a database that does not exist will result in a successful result.

This internally uses IDBFactory::deleteDatabase

pub async fn open( &self, name: &str, version: u32, upgrader: impl 'static + FnOnce(VersionChangeEvent) -> Result<()> ) -> Result<Database>

Open a database

Returns an error if something failed while opening or upgrading the database. Blocks until it can actually open the database.

Note that version must be at least 1. upgrader will be called when version is higher than the previous database version, or upon database creation.

This internally uses IDBFactory::open as well as the methods from IDBOpenDBRequest
