ex_wire v0.1.1 ExWire.Packet.BlockBodies

Eth Wire Packet for getting block bodies from a peer.

**BlockBodies** [`+0x06`, [`transactions_0`, `uncles_0`] , ...]

Reply to `GetBlockBodies`. The items in the list (following the message ID) are
some of the blocks, minus the header, in the format described in the main Ethereum
specification, previously asked for in a `GetBlockBodies` message. This may
validly contain no items if no blocks were able to be returned for the
`GetBlockBodies` query.

Functions

deserialize(rlp)

Given an RLP-encoded BlockBodies packet from Eth Wire Protocol, decodes into a BlockBodies struct

handle(packet)

Handles a BlockBodies message. This is when we have received a given set of blocks back from a peer

serialize(packet)

Given a BlockBodies packet, serializes for transport over Eth Wire Protocol
