$ApiVersionCodec

$RuntimeVersionCodec

ApiVersion

A pairs of ApiId and a u32 for version.

Blake2bHasher

Blake2b hash

Hasher

HttpProvider

The HTTP Provider allows sending requests using HTTP to a HTTP RPC server TCP port. It does not support subscriptions so you won't be able to listen to events such as new blocks or balance changes. It is usually preferable using the [WsProvider]

KeyValue

Provider

ReadProof

ReadProof struct returned by the RPC

RpcResponse<R>

RuntimeMetadata

RuntimeVersion

Runtime version. This should not be thought of as classic Semver (major/minor/tiny). This triplet have different semantics and mis-interpretation could cause problems. In particular: bug fixes should result in an increment of spec_version and possibly authoring_version, absolutely not impl_version since they change the semantics of the runtime.

WsProvider

The WebSocket Provider allows sending requests using WebSocket to a WebSocket RPC server TCP port. Unlike the [HttpProvider], it does support subscriptions and allows listening to events such as new blocks or balance changes.
