Trait Implementations§

source§

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

source§

fn trace_block( &self, block: Block::Hash, targets: Option<String>, storage_keys: Option<String>, methods: Option<String> ) -> RpcResult<TraceBlockResponse>

Re-execute the given block with the tracing targets given in targets and capture all state changes.

Note: requires the node to run with --rpc-methods=Unsafe. Note: requires runtimes compiled with wasm tracing support, --features with-tracing.

source§

fn call( &self, method: String, data: Bytes, block: Option<Block::Hash> ) -> RpcResult<Bytes>

Call a method from the runtime API at a block’s state.
source§

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

Returns the keys with prefix, leave empty to get all the keys.
source§

fn storage_pairs( &self, key_prefix: StorageKey, block: Option<Block::Hash> ) -> RpcResult<Vec<(StorageKey, StorageData)>>

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

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

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.
source§

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

Returns a storage entry at a specific block’s state.
source§

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

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

fn storage_size<'life0, 'async_trait>( &'life0 self, key: StorageKey, block: Option<Block::Hash> ) -> Pin<Box<dyn Future<Output = RpcResult<Option<u64>>> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait,

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

fn metadata(&self, block: Option<Block::Hash>) -> RpcResult<Bytes>

Returns the runtime metadata as an opaque blob.
source§

fn runtime_version(&self, at: Option<Block::Hash>) -> RpcResult<RuntimeVersion>

Get the runtime version.
source§

fn query_storage( &self, keys: Vec<StorageKey>, from: Block::Hash, to: Option<Block::Hash> ) -> RpcResult<Vec<StorageChangeSet<Block::Hash>>>

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

fn query_storage_at( &self, keys: Vec<StorageKey>, at: Option<Block::Hash> ) -> RpcResult<Vec<StorageChangeSet<Block::Hash>>>

Query storage entries (by key) at a block hash given as the second parameter. NOTE: Each StorageChangeSet in the result corresponds to exactly one element – the storage value under an input key at the input block hash.
source§

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

Returns proof of storage entries at a specific block’s state.
source§

fn subscribe_runtime_version( &self, sink: SubscriptionSink ) -> SubscriptionResult

New runtime version subscription
source§

fn subscribe_storage( &self, sink: SubscriptionSink, keys: Option<Vec<StorageKey>> ) -> SubscriptionResult

New storage subscription
source§

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.
