pub struct Client<Hash> { /* fields omitted */ }

The Client.

Implementations

impl<Hash> Client<Hash> where
    Hash: Send + Sync + 'static + DeserializeOwned + Serialize, 

pub fn new(sender: RpcChannel) -> Self

Creates a new Client.

pub fn storage_keys(
    &self,
    child_storage_key: PrefixedStorageKey,
    prefix: StorageKey,
    hash: Option<Hash>
) -> impl Future<Item = Vec<StorageKey>, Error = RpcError>

DEPRECATED: Please use childstate_getKeysPaged with proper paging support. Returns the keys with prefix from a child storage, leave empty to get all the keys

pub fn storage_keys_paged(
    &self,
    child_storage_key: PrefixedStorageKey,
    prefix: Option<StorageKey>,
    count: u32,
    start_key: Option<StorageKey>,
    hash: Option<Hash>
) -> impl Future<Item = Vec<StorageKey>, Error = RpcError>

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.

pub fn storage(
    &self,
    child_storage_key: PrefixedStorageKey,
    key: StorageKey,
    hash: Option<Hash>
) -> impl Future<Item = Option<StorageData>, Error = RpcError>

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

pub fn storage_hash(
    &self,
    child_storage_key: PrefixedStorageKey,
    key: StorageKey,
    hash: Option<Hash>
) -> impl Future<Item = Option<Hash>, Error = RpcError>

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

pub fn storage_size(
    &self,
    child_storage_key: PrefixedStorageKey,
    key: StorageKey,
    hash: Option<Hash>
) -> impl Future<Item = Option<u64>, Error = RpcError>

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

pub fn read_child_proof(
    &self,
    child_storage_key: PrefixedStorageKey,
    keys: Vec<StorageKey>,
    hash: Option<Hash>
) -> impl Future<Item = ReadProof<Hash>, Error = RpcError>

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

Trait Implementations

impl<Hash: Clone> Clone for Client<Hash>

fn clone(&self) -> Client<Hash>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Hash> From<RpcChannel> for Client<Hash> where
    Hash: Send + Sync + 'static + DeserializeOwned + Serialize, 

fn from(channel: RpcChannel) -> Self

Performs the conversion.
