subxt_test

Structs

BlockNumber	Wrapper for NumberOrHex to allow custom From impls
ChargeTransactionPayment	Require the transactor pay for themselves and maybe include a tip to gain additional priority in the queue.
CheckEra	Check for transaction mortality.
CheckGenesis	Check genesis hash
CheckNonce	Nonce check and increment to give replay protection for transactions.
CheckSpecVersion	SignedExtra checks copied from substrate, in order to remove requirement to implement substrate's frame_system::Trait Ensure the runtime version registered in the transaction is the same as at present.
CheckTxVersion	Ensure the transaction version registered in the transaction is the same as at present.
CheckWeight	Resource limit check.
Client	Client to interface with a substrate node.
ClientBuilder	ClientBuilder for constructing a Client.
DefaultExtra	Default SignedExtra for substrate runtimes.
DefaultNodeRuntime	Concrete type definitions compatible with those in the default substrate node_runtime
Encoded	Wraps an already encoded byte vector, prevents being encoded as a raw byte vector as part of the transaction payload
EventSubscription	Event subscription simplifies filtering a storage change set stream for events of interest.
EventsDecoder	Event decoder.
ExtrinsicSuccess	Captures data for when an extrinsic is successfully included in a block
KusamaRuntime	Concrete type definitions compatible with those for kusama, v0.7
Metadata	Runtime metadata.
NodeTemplateRuntime	Concrete type definitions compatible with the node template.
PairSigner	Extrinsic signer using a private key.
RawEvent	Raw bytes for an Event

Enums

Error	Error enum.
MetadataError	Metadata error.

Traits

Call	Call trait.
Event	Event trait.
Runtime	Runtime trait.
SignedExtension	Means by which a transaction may be extended. This type embodies both the data and the logic that should be additionally associated with the transaction. It should be plain old data.
SignedExtra	Trait for implementing transaction extras for a runtime.
Signer	Extrinsic signer.
Store	Store trait.

Type Definitions

Extra	Extra type.
SignedPayload	SignedPayload type.
UncheckedExtrinsic	UncheckedExtrinsic type.
