pub struct State<Block, Client> { /* private fields */ }
Expand description

State API with subscriptions support.

Trait Implementations§

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.

Call a contract at a block’s state.
Returns the keys with prefix, leave empty to get all the keys.
Returns the keys with prefix, leave empty to get all the keys
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. Read more
Returns a storage entry at a specific block’s state.
Returns the hash of a storage entry at a block’s state.
Returns the size of a storage entry at a block’s state.
Returns the runtime metadata as an opaque blob.
Get the runtime version.
Query historical storage entries (by key) starting from a block given as the second parameter. Read more
Query storage entries (by key) starting at block hash given as the second parameter.
Returns proof of storage entries at a specific block’s state.
New runtime version subscription
New storage subscription
Collects all the methods and subscriptions defined in the trait and adds them into a single RpcModule.
