# `Cartouche.Receipt.Log`
[🔗](https://github.com/zenhive/cartouche/blob/main/lib/cartouche/receipt.ex#L13)

An event log entry emitted during the transaction referenced by a
`Cartouche.Receipt` — address, data, indexed topics, and the block/tx
position needed to locate the log on chain.

# `t`

```elixir
@type t() :: %Cartouche.Receipt.Log{
  address: <<_::160>>,
  block_hash: <<_::256>>,
  block_number: integer(),
  data: binary(),
  log_index: integer(),
  topics: [<<_::256>>],
  transaction_hash: <<_::256>>,
  transaction_index: integer()
}
```

# `deserialize`

```elixir
@spec deserialize(map()) :: t() | no_return()
```

Deserializes a transaction receipt as serialized by an Ethereum JSON-RPC response.
