blockchain v0.1.5 Blockchain.Transaction.Receipt

This module specifies functions to create and interact with the transaction receipt, defined in Section 4.4.1 of the Yellow Paper.

Transaction receipts track incremental state changes after each transaction (e.g. how much gas has been expended).

Functions

deserialize(rlp)

Decodes a transaction receipt based on the serialization format defined in Eq.(20). This is the inverse of serialize/1

serialize(trx_receipt)

Encodes a transaction receipt such that it can be RLP encoded. This is defined in Eq.(20) of the Yellow Paper

t() :: %Blockchain.Transaction.Receipt{bloom_filter: binary, cumulative_gas: EVM.Gas.t, logs: EVM.SubState.logs, state: EVM.trie_root}

Link to this function deserialize(rlp) 
deserialize(ExRLP.t) :: t

Decodes a transaction receipt based on the serialization format defined in Eq.(20). This is the inverse of serialize/1.

Examples

iex> Blockchain.Transaction.Receipt.deserialize([<<1,2,3>>, <<5>>, <<2,3,4>>, “hi mom”]) %Blockchain.Transaction.Receipt{state: <<1,2,3>>, cumulative_gas: 5, bloom_filter: <<2,3,4>>, logs: “hi mom”}

iex> Blockchain.Transaction.Receipt.deserialize([<<>>, <<0>>, <<>>, <<>>]) %Blockchain.Transaction.Receipt{}

Link to this function serialize(trx_receipt) 
serialize(t) :: ExRLP.t

Encodes a transaction receipt such that it can be RLP encoded. This is defined in Eq.(20) of the Yellow Paper.

Examples 

iex> Blockchain.Transaction.Receipt.serialize(%Blockchain.Transaction.Receipt{})
[<<>>, 0, <<>>, <<>>]

iex> Blockchain.Transaction.Receipt.serialize(%Blockchain.Transaction.Receipt{state: <<1,2,3>>, cumulative_gas: 5, bloom_filter: <<2,3,4>>, logs: "hi mom"})
[<<1,2,3>>, 5, <<2,3,4>>, "hi mom"]
