pub struct ChildState<Block, Client> { /* private fields */ }

Child state API with subscriptions support.

Trait Implementations

impl<Block, Client> ChildStateApiServer<<Block as Block>::Hash> for ChildState<Block, Client>where Block: BlockT + 'static, Client: Send + Sync + 'static,

fn storage_keys( &self, storage_key: PrefixedStorageKey, key_prefix: StorageKey, block: Option<Block::Hash> ) -> RpcResult<Vec<StorageKey>>

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

fn storage_keys_paged( &self, storage_key: PrefixedStorageKey, prefix: Option<StorageKey>, count: u32, start_key: Option<StorageKey>, block: Option<Block::Hash> ) -> RpcResult<Vec<StorageKey>>

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.

fn storage( &self, storage_key: PrefixedStorageKey, key: StorageKey, block: Option<Block::Hash> ) -> RpcResult<Option<StorageData>>

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

fn storage_entries( &self, storage_key: PrefixedStorageKey, keys: Vec<StorageKey>, block: Option<Block::Hash> ) -> RpcResult<Vec<Option<StorageData>>>

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

fn storage_hash( &self, storage_key: PrefixedStorageKey, key: StorageKey, block: Option<Block::Hash> ) -> RpcResult<Option<Block::Hash>>

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

fn storage_size( &self, storage_key: PrefixedStorageKey, key: StorageKey, block: Option<Block::Hash> ) -> RpcResult<Option<u64>>

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

fn read_child_proof( &self, child_storage_key: PrefixedStorageKey, keys: Vec<StorageKey>, block: Option<Block::Hash> ) -> RpcResult<ReadProof<Block::Hash>>

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

fn into_rpc(self) -> RpcModule<Self>where Hash: Send + Sync + 'static + DeserializeOwned + Serialize,

Collects all the methods and subscriptions defined in the trait and adds them into a single RpcModule.
