Expand description

An ethereum network request for version 66.

The network layer aims to abstract away the details of the Ethereum wire protocol into a clear request/response API. Each Request documents the possible Responses it can generate; it is fine (and recommended!) to match on the expected responses and treat the others as unreachable!(), since their return indicates a bug in the network code.

Variants

`Status(Status)`

The Status message sent as part of the eth protocol handshake.

Response

A peer should return a Response::Status in response to complete the protocol handshake.

`NewBlockHashes(NewBlockHashes)`

A list of observed block hashes to be broadcasted.

Response

Returns Response::Nil.

`NewBlock(Box<NewBlock>)`

A new block to be broadcasted.

Response

Return Response::Nil.

`Transactions(Transactions)`

A list of observed transactions to be broadcasted.

Response

Returns Response::Nil.

`NewPooledTransactionHashes(NewPooledTransactionHashes)`

A list of observed transaction hashes to be broadcasted.

Response

Returns Response::Nil.

`GetBlockHeaders(RequestPair<GetBlockHeaders>)`

Request block headers from a peer.

Response

Returns Response::BlockHeaders.

`GetBlockBodies(RequestPair<GetBlockBodies>)`

Request block bodies from a peer.

Response

Returns Response::BlockBodies.

`GetPooledTransactions(RequestPair<GetPooledTransactions>)`

Request transaction bodies from a peer.

Response

Returns Response::PooledTransactions.

`GetNodeData(RequestPair<GetNodeData>)`

Request state data from a peer.

Response

Returns Response::NodeData.

`GetReceipts(RequestPair<GetReceipts>)`

Request transaction receipts from a peer.

Response

Returns Response::Receipts.
