Modules

chain_ops

Chain utilities.

config

Service configuration.

error

Errors that can occur during the service operation.

Structs

BuildNetworkParams

Parameters to pass into build_network.

ClientConfig

Relevant client configuration items relevant for the client.

GenericChainSpec

A configuration of a chain. Can be used to build a genesis block.

KeystoreContainer

Construct and hold different layers of Keystore wrappers

LocalCallExecutor

Call executor that executes methods locally, querying all required data from local backend.

NetworkStarter

Object used to start the network.

NetworkStatusSinks

Sinks to propagate network status updates. For each element, every time the Interval fires we push an element on the sender.

NoopRpcExtensionBuilder

A utility struct for implementing an RpcExtensionBuilder given a cloneable RpcExtension, the resulting builder will simply ignore the provided DenyUnsafe instance and return a static RpcExtension instance.

PartialComponents

An incomplete set of chain components, but enough to run the chain ops subcommands.

RpcHandlers

RPC handlers that can perform RPC queries.

RpcMetadata

RPC Metadata.

RpcSession

An RPC session. Used to perform in-memory RPC queries (ie. RPC queries that don’t go through the HTTP or WebSockets server).

SpawnTaskHandle

An handle for spawning tasks in the service.

SpawnTasksParams

Parameters to pass into build.

TaskManager

Helper struct to manage background/async tasks in Service.

TransactionPoolAdapter

Transaction pool adapter.

TransactionPoolOptions

Pool configuration options.

Enums

ChainType

The type of a chain.

DatabaseConfig

Where to find the database..

KeepBlocks

Block pruning settings.

PruningMode

Pruning mode.

Role

Role of the local node.

TracingReceiver

Used to configure how to receive the metrics

TransactionStorageMode

Block body storage scheme.

Traits

ChainSpec

Common interface of a chain specification.

ChainSpecExtension

A collection of ChainSpec extensions.

ImportQueue

Blocks import queue API.

InPoolTransaction

In-pool transaction interface.

IntoPoolError

Transaction pool error conversion.

MallocSizeOfWasm

A type that implements MallocSizeOf on native but not wasm.

NativeExecutionDispatch

Delegate for dispatching a CodeExecutor call.

RpcExtensionBuilder

A utility trait for building an RPC extension given a DenyUnsafe instance. This is useful since at service definition time we don’t know whether the specific interface where the RPC extension will be exposed is safe or not. This trait allows us to lazily build the RPC extension whenever we bind the service to an interface.

RuntimeGenesis

A set of traits for the runtime genesis config.

TransactionPool

Transaction pool interface.

Functions

build_network

Build the network service, the network status sinks and an RPC sender.

build_offchain_workers

Build a shared offchain workers instance.

new_client

Create an instance of db-backed client.

new_full_client

Creates a new full client for the given config.

new_full_parts

Create the initial parts of a full node.

new_light_parts

Create the initial parts of a light node.

spawn_tasks

Spawn the tasks that are required to run a node.

Type Definitions

NoExtension

A type denoting empty extensions.

Properties

Arbitrary properties defined in chain spec as a JSON object

TFullBackend

Full client backend type.

TFullCallExecutor

Full client call executor type.

TFullClient

Full client type.

TLightBackend

Light client backend type.

TLightBackendWithHash

Light client backend type with a specific hash type.

TLightCallExecutor

Light call executor type.

TLightClient

Light client type.

TLightClientWithBackend

Light client type with a specific backend.
