Expand description

Client implementation for the ChildStateApi RPC API.

Provided Methods§

source

fn storage_keys<'life0, 'async_trait>( &'life0 self, child_storage_key: PrefixedStorageKey, prefix: StorageKey, hash: Option<Hash>, ) -> Pin<Box<dyn Future<Output = Result<Vec<StorageKey>, Error>> + Send + 'async_trait>>
where 'life0: 'async_trait, Self: Sync + 'async_trait,

👎Deprecated since 2.0.0: Please use getKeysPaged with proper paging support

Returns the keys with prefix from a child storage, leave empty to get all the keys

source

fn storage_keys_paged<'life0, 'async_trait>( &'life0 self, child_storage_key: PrefixedStorageKey, prefix: Option<StorageKey>, count: u32, start_key: Option<StorageKey>, hash: Option<Hash>, ) -> Pin<Box<dyn Future<Output = Result<Vec<StorageKey>, Error>> + Send + 'async_trait>>
where 'life0: 'async_trait, Self: Sync + 'async_trait,

Returns the keys with prefix from a child storage with pagination support. Up to count keys will be returned. If start_key is passed, return next keys in storage in lexicographic order.

source

fn storage<'life0, 'async_trait>( &'life0 self, child_storage_key: PrefixedStorageKey, key: StorageKey, hash: Option<Hash>, ) -> Pin<Box<dyn Future<Output = Result<Option<StorageData>, Error>> + Send + 'async_trait>>
where 'life0: 'async_trait, Self: Sync + 'async_trait,

Returns a child storage entry at a specific block’s state.

source

fn storage_entries<'life0, 'async_trait>( &'life0 self, child_storage_key: PrefixedStorageKey, keys: Vec<StorageKey>, hash: Option<Hash>, ) -> Pin<Box<dyn Future<Output = Result<Vec<Option<StorageData>>, Error>> + Send + 'async_trait>>
where 'life0: 'async_trait, Self: Sync + 'async_trait,

Returns child storage entries for multiple keys at a specific block’s state.

source

fn storage_hash<'life0, 'async_trait>( &'life0 self, child_storage_key: PrefixedStorageKey, key: StorageKey, hash: Option<Hash>, ) -> Pin<Box<dyn Future<Output = Result<Option<Hash>, Error>> + Send + 'async_trait>>
where 'life0: 'async_trait, Self: Sync + 'async_trait,

Returns the hash of a child storage entry at a block’s state.

source

fn storage_size<'life0, 'async_trait>( &'life0 self, child_storage_key: PrefixedStorageKey, key: StorageKey, hash: Option<Hash>, ) -> Pin<Box<dyn Future<Output = Result<Option<u64>, Error>> + Send + 'async_trait>>
where 'life0: 'async_trait, Self: Sync + 'async_trait,

Returns the size of a child storage entry at a block’s state.

source

fn read_child_proof<'life0, 'async_trait>( &'life0 self, child_storage_key: PrefixedStorageKey, keys: Vec<StorageKey>, hash: Option<Hash>, ) -> Pin<Box<dyn Future<Output = Result<ReadProof<Hash>, Error>> + Send + 'async_trait>>
where 'life0: 'async_trait, Self: Sync + 'async_trait,

Returns proof of storage for child key entries at a specific block’s state.

Object Safety§

This trait is not object safe.
