Struct indexed_db::ObjectStore

pub struct ObjectStore<Err> { /* private fields */ }

Wrapper for IDBObjectStore, for use in transactions

Implementations

impl<Err> ObjectStore<Err>

pub fn add( &self, value: &JsValue ) -> impl Future<Output = Result<JsValue, Error<Err>>>

Add the value val to this object store, and return its auto-computed key

This will error if the key already existed.

Internally, this uses IDBObjectStore::add.

pub fn add_kv( &self, key: &JsValue, value: &JsValue ) -> impl Future<Output = Result<(), Error<Err>>>

Add the value val to this object store, with key key

This will error if the key already existed.

Internally, this uses IDBObjectStore::add.

pub fn put( &self, value: &JsValue ) -> impl Future<Output = Result<JsValue, Error<Err>>>

Sets the value val to this object store, and return its auto-computed key

This will overwrite the previous value if the key already existed.

Internally, this uses IDBObjectStore::add.

pub fn put_kv( &self, key: &JsValue, value: &JsValue ) -> impl Future<Output = Result<(), Error<Err>>>

Add the value val to this object store, with key key

This will overwrite the previous value if the key already existed.

Internally, this uses IDBObjectStore::add.

pub fn clear(&self) -> impl Future<Output = Result<(), Error<Err>>>

Clears this object store

Internally, this uses IDBObjectStore::clear.

pub fn count(&self) -> impl Future<Output = Result<usize, Error<Err>>>

Counts the number of objects in this store

Internally, this uses IDBObjectStore::count.

pub fn contains( &self, key: &JsValue ) -> impl Future<Output = Result<bool, Error<Err>>>

Checks whether the provided key exists in this object store

Internally, this uses IDBObjectStore::count.

pub fn count_in( &self, range: impl RangeBounds<JsValue> ) -> impl Future<Output = Result<usize, Error<Err>>>

Counts the number of objects with a key in range

Note that the unbounded range is not a valid range for IndexedDB.

Internally, this uses IDBObjectStore::count.

pub fn delete( &self, key: &JsValue ) -> impl Future<Output = Result<(), Error<Err>>>

Delete the object with key key

Unfortunately, the IndexedDb API does not indicate whether an object was actually deleted.

Internally, this uses IDBObjectStore::delete.

pub fn delete_range( &self, range: impl RangeBounds<JsValue> ) -> impl Future<Output = Result<(), Error<Err>>>

Delete all the objects with a key in range

Note that the unbounded range is not a valid range for IndexedDB. Unfortunately, the IndexedDb API does not indicate whether an object was actually deleted.

Internally, this uses IDBObjectStore::delete.

pub fn get( &self, key: &JsValue ) -> impl Future<Output = Result<Option<JsValue>, Error<Err>>>

Get the object with key key

Internally, this uses IDBObjectStore::get.

pub fn get_first_in( &self, range: impl RangeBounds<JsValue> ) -> impl Future<Output = Result<Option<JsValue>, Error<Err>>>

Get the first value with a key in range, ordered by key

Note that the unbounded range is not a valid range for IndexedDB.

Internally, this uses IDBObjectStore::get.

pub fn get_all( &self, limit: Option<u32> ) -> impl Future<Output = Result<Vec<JsValue>, Error<Err>>>

Get all the objects in the store, with a maximum number of results of limit

Internally, this uses IDBObjectStore::getAll.

pub fn get_all_in( &self, range: impl RangeBounds<JsValue>, limit: Option<u32> ) -> impl Future<Output = Result<Vec<JsValue>, Error<Err>>>

Get all the objects with a key in the provided range, with a maximum number of results of limit

Internally, this uses IDBObjectStore::getAll.

pub fn get_first_key_in( &self, range: impl RangeBounds<JsValue> ) -> impl Future<Output = Result<Option<JsValue>, Error<Err>>>

Get the first existing key in the provided range

Internally, this uses IDBObjectStore::getKey.

pub fn get_all_keys( &self, limit: Option<u32> ) -> impl Future<Output = Result<Vec<JsValue>, Error<Err>>>

List all the keys in the object store, with a maximum number of results of limit

Internally, this uses IDBObjectStore::getAllKeys.

pub fn get_all_keys_in( &self, range: impl RangeBounds<JsValue>, limit: Option<u32> ) -> impl Future<Output = Result<Vec<JsValue>, Error<Err>>>

List all the keys in the provided range, with a maximum number of results of limit

Internally, this uses IDBObjectStore::getAllKeys.

pub fn index(&self, name: &str) -> Result<Index<Err>, Error<Err>>

Get the Index with the provided name

Internally, this uses IDBObjectStore::index.
