ethereum-toolkit

Basic Rust code for parsing Ethereum and Ethereum Classic Block JSON logs. When looking at Eth logs, I like to start with Python or Ruby interactively in a REPL. But then for repeatable, working code, I prefer a well typed language like Rust. Once a number of support functions and definitions are written, I find it faster to work with data. This repo contains much of this basic support, including Newtypes for simple value types and structs for strongly typed JSON deserialization.

I wrote this to create scripts, leveraging Rust’s great type system. The code assumes there’s a JSON file with an array of Blocks and their transactions.

To use it, change the file path at the top to point to a log file you want to inspect:

const FILE_DATA: &str = include_str!("../eth_log.json");

Then add code to the main() function to examine and query the blockchain:

fn main() {     let blockchain_file: Blockchain = serde_json::from_str(FILE_DATA).unwrap();     let cleaned_up_blockchain = blockchain_file.de_dup();     let common_ancestors = duplicated_parents(&cleaned_up_blockchain);     let _block_by_hash = make_lookup_by_hash(&cleaned_up_blockchain);      println!(         "Number of duplicate Parent references (reorgs): {}n",         common_ancestors.len()     ); }

以太坊eth工具箱

用于解析以太坊eth和以太坊eth经典块JSON日志的基本Rust代码。在查看Eth日志时，我喜欢在REPL中以交互方式从Python或Ruby开始。但是对于可重复的工作代码，我更喜欢像Rust这样的类型良好的语言。一旦编写了许多支持函数和定义，我发现处理数据会更快。这个repo包含很多基本的支持，包括简单值类型的newtype和强类型JSON反序列化的struct。

我写这篇文章是为了创建脚本，利用Rust强大的类型系统。代码假定有一个JSON文件，其中包含一个块数组及其事务。

要使用它，请更改顶部的文件路径以指向要检查的日志文件：

const FILE_DATA: &str = include_str!("../eth_log.json");

然后向main（）函数添加代码，以检查和查询区块链blockchain：

fn main() {     let blockchain_file: Blockchain = serde_json::from_str(FILE_DATA).unwrap();     let cleaned_up_blockchain = blockchain_file.de_dup();     let common_ancestors = duplicated_parents(&cleaned_up_blockchain);     let _block_by_hash = make_lookup_by_hash(&cleaned_up_blockchain);      println!(         "Number of duplicate Parent references (reorgs): {}n",         common_ancestors.len()     ); }
