Implementations

impl<Hash> Client<Hash> where
    Hash: Send + Sync + 'static + DeserializeOwned + Serialize
[src]

pub fn new(sender: RpcChannel) -> Client<Hash>[src]

Creates a new Client.

pub fn call(
    &self,
    name: String,
    bytes: Bytes,
    hash: Option<Hash>
) -> impl Future<Item = Bytes, Error = RpcError>
[src]

Call a contract at a block's state.

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

DEPRECATED: Please use state_getKeysPaged with proper paging support. Returns the keys with prefix, leave empty to get all the keys.

pub fn storage_pairs(
    &self,
    prefix: StorageKey,
    hash: Option<Hash>
) -> impl Future<Item = Vec<(StorageKey, StorageData)>, Error = RpcError>
[src]

Returns the keys with prefix, leave empty to get all the keys

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

Returns the keys with prefix 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,
    key: StorageKey,
    hash: Option<Hash>
) -> impl Future<Item = Option<StorageData>, Error = RpcError>
[src]

Returns a storage entry at a specific block's state.

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

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

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

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

pub fn metadata(
    &self,
    hash: Option<Hash>
) -> impl Future<Item = Bytes, Error = RpcError>
[src]

Returns the runtime metadata as an opaque blob.

pub fn runtime_version(
    &self,
    hash: Option<Hash>
) -> impl Future<Item = RuntimeVersion, Error = RpcError>
[src]

Get the runtime version.

pub fn query_storage(
    &self,
    keys: Vec<StorageKey>,
    block: Hash,
    hash: Option<Hash>
) -> impl Future<Item = Vec<StorageChangeSet<Hash>>, Error = RpcError>
[src]

Query historical storage entries (by key) starting from a block given as the second parameter.

NOTE This first returned result contains the initial state of storage for all keys. Subsequent values in the vector represent changes to the previous state (diffs).

pub fn query_storage_at(
    &self,
    keys: Vec<StorageKey>,
    at: Option<Hash>
) -> impl Future<Item = Vec<StorageChangeSet<Hash>>, Error = RpcError>
[src]

Query storage entries (by key) starting at block hash given as the second parameter.

pub fn read_proof(
    &self,
    keys: Vec<StorageKey>,
    hash: Option<Hash>
) -> impl Future<Item = ReadProof<Hash>, Error = RpcError>
[src]

Returns proof of storage entries at a specific block's state.

pub fn subscribe_runtime_version(
    &self
) -> impl Future<Item = TypedSubscriptionStream<RuntimeVersion>, Error = RpcError>
[src]

New runtime version subscription

pub fn subscribe_storage(
    &self,
    keys: Option<Vec<StorageKey>>
) -> impl Future<Item = TypedSubscriptionStream<StorageChangeSet<Hash>>, Error = RpcError>
[src]

New storage subscription
