Summary of Changes

Hello @jcstein, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on enhancing and expanding the project's documentation. It includes updates to client library documentation, specifically for Go and introducing a new Rust client, and a comprehensive rewrite of the "Private Data Availability" feature explanation, now termed "Private Blockspace," to provide clearer insights into its functionality and applications.

Highlights

  • Documentation Updates: Updated descriptions for "Light Node" to "Self-hosted light node" in metadata.
  • Go Client Documentation: Renamed the existing Go client tutorial page for clarity.
  • Rust Client Documentation: Introduced a new documentation page for the celestia-client Rust library, detailing its features and modes.
  • Private Blockspace Feature: Significantly revised the "Private data availability" page, renaming it to "Private blockspace" and adding detailed sections on its mechanics, use cases, and getting started.

Code Review

This pull request provides several documentation updates, including a significant rewrite of the 'Private Blockspace' page, the addition of a new page for the Rust client, and other minor adjustments. The changes greatly improve the clarity and structure of the documentation. I have one suggestion for the new Rust client page to enhance formatting and clarify that it's a community-developed client, which will help manage user expectations.

## (`celestia-client`)

Lumina’s Rust client library provides a high-level API for interacting with a Celestia node over RPC and gRPC. It builds on top of the lower-level `celestia-rpc` and `celestia-grpc` crates and exposes a unified `Client` that supports both **read-only** and **submit** modes. In read-only mode, the client connects to a node via RPC (and optionally gRPC) to query headers, blobs, and state. In submit mode, it additionally uses gRPC and a local signer to build, sign, and broadcast transactions such as transfers and PayForBlobs. The crate re-exports common Celestia types (namespaces, blobs, app versions, etc.) and is designed to be the easiest way for Rust applications to integrate with Celestia nodes for data retrieval, blob submission, and general chain interaction. ([lib.rs][1])

A couple of suggestions to improve clarity and formatting on this new page:

  1. The parentheses in the subtitle (\celestia-client`)` are unconventional for a Markdown heading. It's clearer to just use backticks for the crate name.
  2. Referring to the client as "Lumina’s Rust client library" might be confusing, as it could imply it's an official client. Since it's a community-developed client, it's better to refer to it by its crate name, celestia-client, to align with the title and manage user expectations about support.
