Struct indexed_db::Index

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

Wrapper for IDBIndex, for use in transactions

Implementations

impl<Err> Index<Err>

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

Count all the keys (for this index) in the provided range

Internally, this uses IDBIndex::count.

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

Get the object with key key for this index

Internally, this uses IDBIndex::get.

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

Get the first value with a key (for this index) in range, ordered by key (for this index)

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

Internally, this uses IDBIndex::get.

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

Get all the objects in the store, ordered by this index, with a maximum number of results of limit

Internally, this uses IDBIndex::getAll.

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

Get all the objects with a key (for this index) in the provided range, with a maximum number of results of limit, ordered by this index

Internally, this uses IDBIndex::getAll.

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

Get the first existing key (for this index) in the provided range

Internally, this uses IDBIndex::getKey.

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

List all the keys in the object store, with a maximum number of results of limit, ordered by this index

Internally, this uses IDBIndex::getAllKeys.

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

List all the keys (for this index) in the provided range, with a maximum number of results of limit, ordered by this index

Internally, this uses IDBIndex::getAllKeys.
