Methods

getPeerInfo

getPeerInfo(value: PeerInfo): Promise<PeerInfo>
Handshake and versioning exchange. Target waits to receive the fuzzer's PeerInfo message before sending its own.
Parameters
- value: PeerInfo
Returns Promise<PeerInfo>
- Defined in packages/jam/fuzz-proto/v1/handler.ts:30

getSerializedState

getSerializedState(
value: OpaqueHash & WithOpaque<"HeaderHash">,
): Promise<KeyValue[]>
Retrieve posterior state associated to given header hash.
Parameters
- value: OpaqueHash & WithOpaque<"HeaderHash">
Returns Promise<KeyValue[]>
- Defined in packages/jam/fuzz-proto/v1/handler.ts:45

importBlock

importBlock(
value: ViewOf,
): Promise<
utils.Result<OpaqueHash & WithOpaque<"StateRootHash">, ErrorMessage>,
>
Process block and return resulting state root. May return an Error if the block import fails.
Parameters
- value: ViewOf
Returns Promise<utils.Result<OpaqueHash & WithOpaque<"StateRootHash">, ErrorMessage>>
- Defined in packages/jam/fuzz-proto/v1/handler.ts:42

initialize

initialize(
header: Initialize,
): Promise<OpaqueHash & WithOpaque<"StateRootHash">>
Initialize or reset target state. Returns the state root of the initialized state.
Parameters
- header: Initialize
Returns Promise<OpaqueHash & WithOpaque<"StateRootHash">>
- Defined in packages/jam/fuzz-proto/v1/handler.ts:36
