fuel-data-parser 0.0.33

A parser for Fuel blockchain data structures and formats
Documentation

📝 About The Project

The Fuel Data Parser is a specialized utility library that provides functionality for efficient encoding and decoding of data within the Fuel Data Systems project. It offers a consistent interface for serialization and deserialization operations, focusing on performance and reliability when handling Fuel blockchain data.

This library provides:

  • A unified interface for serialization/deserialization of data structures
  • Support for JSON serialization with potential for expansion to other formats
  • A trait-based system for easy implementation on custom data types
  • Error handling tailored for data parsing operations

[!NOTE] This crate is primarily designed for internal use within the Fuel Data Systems project, serving as a foundational utility for other components that need to encode or decode data.

🛠️ Installing

Add this dependency to your Cargo.toml:

[dependencies]
fuel-data-parser = "0.1.0"  # Use the latest version available

🚀 Features

The fuel-data-parser crate provides several key features:

  • Consistent API: Unified interface for all serialization/deserialization operations
  • JSON Support: Built-in support for JSON encoding and decoding
  • Error Handling: Comprehensive error types for debugging serialization issues
  • Extensible Design: Architecture that allows for additional serialization formats
  • Trait-Based System: Easy implementation on custom data types through the DataEncoder trait

📊 Usage

Basic Usage

Here's a basic example of using the DataParser to encode and decode data:

use fuel_data_parser::{DataEncoder, DataParser, SerializationType};
use serde::{Serialize, Deserialize};

// Define a data structure
#[derive(Debug, Clone, Serialize, Deserialize, PartialEq)]
struct UserData {
    id: u64,
    name: String,
    active: bool,
}

// Implement the DataEncoder trait
impl DataEncoder for UserData {}

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create a DataParser with the default configuration (JSON)
    let parser = DataParser::default();

    // Create some data
    let user = UserData {
        id: 1,
        name: "Alice".to_string(),
        active: true,
    };

    // Encode the data to JSON
    let encoded_data = parser.encode_json(&user)?;
    println!("Encoded data size: {} bytes", encoded_data.len());

    // Decode the data back to the original type
    let decoded_user: UserData = parser.decode_json(&encoded_data)?;
    println!("Decoded user: {:?}", decoded_user);

    // Verify equality
    assert_eq!(user, decoded_user);

    Ok(())
}

Using the DataEncoder Trait

The DataEncoder trait provides convenience methods for common operations:

use fuel_data_parser::{DataEncoder, DataParser};
use serde::{Serialize, Deserialize};

#[derive(Debug, Clone, Serialize, Deserialize)]
struct BlockData {
    height: u64,
    hash: String,
    timestamp: u64,
}

// Implement DataEncoder to get encode/decode methods
impl DataEncoder for BlockData {}

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let block = BlockData {
        height: 100,
        hash: "0x123abc...".to_string(),
        timestamp: 1625097600,
    };

    // Use trait methods directly on the data
    let encoded = block.encode_json()?;

    // Use static methods for decoding
    let decoded = BlockData::decode_json(&encoded)?;

    // Convert to JSON value for custom processing
    let json_value = block.to_json_value()?;
    println!("Block JSON: {}", json_value);

    Ok(())
}

Using in Async Contexts

The DataParser can be used in async code:

use fuel_data_parser::{DataEncoder, DataParser};
use serde::{Serialize, Deserialize};

#[derive(Debug, Clone, Serialize, Deserialize)]
struct NetworkMessage {
    message_type: String,
    payload: Vec<u8>,
}

impl DataEncoder for NetworkMessage {}

async fn process_message(message: &NetworkMessage) -> Result<Vec<u8>, Box<dyn std::error::Error>> {
    let parser = DataParser::default();

    // In a real application, this might involve network operations
    let encoded = parser.encode_json(message)?;

    Ok(encoded)
}

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let message = NetworkMessage {
        message_type: "data".to_string(),
        payload: vec![1, 2, 3, 4],
    };

    let encoded = process_message(&message).await?;
    println!("Encoded message size: {} bytes", encoded.len());

    Ok(())
}

🏎️ Benchmarks

To run the benchmarks and measure performance of the serialization operations:

cargo bench -p fuel-data-parser

The benchmarks compare different operations and can help you understand the performance characteristics of the library.
