Proposal

Request for funding to support the development of a Rust SDK for Qubic, aimed at providing developers with a simple, type-safe, and efficient interface for interacting with Qubic's RPC APIs. The total requested amount is USD 31,200, covering development, testing, and documentation costs over the next 3 months.

Available Options:

Option 0: No, I don’t want

Option 1: Yes, allocate the equivalent amount in QUBIC

Details

What is the Rust SDK for Qubic?

The Rust SDK for Qubic will provide a comprehensive, developer-friendly toolkit to integrate with Qubic's RPC APIs. Leveraging Rust's strong type system and asynchronous capabilities, the SDK aims to streamline interactions with Qubic, ensuring type safety, efficiency, and ease of use for developers.

Planned features include:

  • Core API support for retrieving ticks, balances, transactions, and smart contract data.
  • Developer utilities for error handling, logging, and JSON serialization.
  • Extensibility to accommodate future endpoints and features.

The Team

A dedicated team will focus on building the Rust SDK for Qubic. Roles include:

  • Technical Lead

    • Required: Experience in Rust development and SDK design.
    • Focus on architecture, core module implementation, and performance optimization.

  • Backend Developer

    • Required: Strong experience in Rust async programming.
    • Focus on implementing RPC endpoints and handling asynchronous operations.

  • Test Engineer

    • Required: Experience with unit and integration testing in Rust.
    • Focus on writing robust test cases and setting up mock API environments.

  • Documentation Specialist

    • Required: Familiarity with rustdoc and technical writing for developers.
    • Focus on inline documentation, examples, and API references.

Technical Implementation Overview

Key Enhancements

  1. Core Modules

    • Client Module: Handles API requests, including headers, retries, and error management.
    • Endpoint Modules: Implements functionalities like balances, transactions, and smart_contracts.
    • Error Handling: Defines custom error types for network issues and API errors.
    • Utilities: Provides helper functions for tasks like URL construction and input validation.

  2. Supported Endpoints

Ticks

  • /latestTick
  • /ticks/{tickNumber}/tick-data
  • /ticks/{tickNumber}/approved-transactions
  • /ticks/{tickNumber}/chain-hash
  • /ticks/{tickNumber}/quorum-tick-data
  • /ticks/{tickNumber}/store-hash

Transactions

  • /broadcast-transaction
  • /tx-status/{txId}
  • /v1/transactions/{txId}
  • /v1/tx-status/{txId}
  • /v1/identities/{identity}/transfer-transactions

Balances

  • /balances/{addressID}
  • /balances/{id}

Smart Contracts

  • /querySmartContract

Assets

  • /assets/{identity}/issued
  • /assets/{identity}/owned
  • /assets/{identity}/possessed

Miscellaneous

  • /status
  • /block-height
  • /v1/healthcheck
  • /v1/latest-stats
  1. Development Workflow

  • Initialization

    • Set up the Rust project using cargo.
    • Integrate reqwest for HTTP requests, tokio for async runtime, and serde for JSON parsing.

  • Module Implementation

    • Develop the Client module to handle API requests.
    • Implement endpoint-specific modules, starting with high-priority features like transactions and balances.

  • Testing

    • Write unit tests using mock API responses.
    • Develop integration tests against a live test API.

  • Documentation

    • Add inline documentation using rustdoc.
    • Provide example usage in the examples/ directory.

  • Release

    • Publish the library to crates.io with a comprehensive README.

Project Timeline and Milestones

Phase 1: Foundation (Month 1)

  • Set up the project and initialize the core modules.
  • Implement basic functionality for retrieving ticks and balances.
  • Establish the testing framework and write initial unit tests.
