§HyperSync Format

Core data types and serialization formats for the HyperSync protocol.

This crate provides the fundamental data structures used to represent blockchain data in a standardized format, including blocks, transactions, logs, and traces.

§Features

  • Standard blockchain types: Comprehensive data structures for Ethereum-compatible chains
  • Efficient serialization: Optimized JSON and binary serialization
  • Type safety: Strong typing for addresses, hashes, and numeric values
  • Hex encoding: Automatic handling of hexadecimal encoding/decoding

§Key Types

  • Block - Complete block data including header and body
  • Transaction - Transaction data with all fields
  • Log - Event log from contract execution
  • Trace - Execution trace information
  • Address - 20-byte Ethereum address
  • [Hash] - 32-byte cryptographic hash
  • Hex - Wrapper for hexadecimal data

§Example

use hypersync_format::{Address, Hash};

// Parse an Ethereum address  
let addr: Address = "0x742d35Cc6634C0532925a3b8D400ACDCD5C94C33".parse()?;
println!("Address: {}", addr);

// Create a hash from hex string  
let hash: Hash = "0x1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef".parse()?;
println!("Hash: {}", hash);
