refactor: splitting up the large files into modules

[distractedm1nd]

splits da.rs and node_types.rs into modules

[coderabbitai]

Walkthrough

The updates focus on restructuring the project by refining imports, reassigning modules, and introducing a new Celestia-based data availability layer. The changes include removing unnecessary dependencies, adding new implementations for data availability, modifying the structure of the LightClient and Sequencer, and reorganizing various module imports.

Changes

File/Path	Change Summary
Cargo.toml	Removed the version specification for the dirs dependency.
src/cfg.rs	Restructured imports for CelestiaConnection and LocalDataAvailabilityLayer.
src/da/celestia.rs	Introduced a new module implementing a data availability layer using the Celestia protocol, including the CelestiaConnection struct and related methods.
src/da/mock.rs	Removed Celestia-related imports and data structures, focusing on mock implementations for NoopDataAvailabilityLayer and LocalDataAvailabilityLayer.
src/da/mod.rs	Added a new module for Data Availability Layer (DAL) implementation, including the definition of an EpochJson struct and a DataAvailabilityLayer trait with various async methods.
src/main.rs	Modified import statements for LightClient, Sequencer, and NodeType to reflect their new submodule locations.
src/node_types/lightclient.rs	Introduced a LightClient struct implementing the NodeType trait with functionality for verifying epochs, handling data availability, and managing header synchronization.
src/node_types/mod.rs	Added submodules lightclient and sequencer, and defined a NodeType trait with an async start method.
src/node_types/sequencer.rs	Removed the NodeType trait and LightClient struct, with the Sequencer struct now directly implementing the NodeType trait.
src/webserver.rs	Updated the import statement for the Sequencer type to reflect its new location in the node_types::sequencer module.

Additional comments not posted (18)

src/main.rs (1)

17-17: LGTM! But verify the usage of modified imports.

The import statements have been correctly updated to reflect the new submodule locations.

However, ensure that all usages of LightClient and Sequencer in the codebase are updated accordingly.

Verification successful

---

Imports updated correctly and consistently.

The import statements for LightClient and Sequencer have been updated correctly across the codebase, and no instances of the old import paths were found.

• src/main.rs
• src/webserver.rs
• src/cfg.rs

Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify all usages of `LightClient` and `Sequencer` in the codebase.

# Test: Search for the usage of `LightClient` and `Sequencer`. Expect: Only occurrences of the new import paths.
rg --type rust -A 5 $'LightClient'
rg --type rust -A 5 $'Sequencer'

Tips

Chat

There are 3 ways to chat with CodeRabbit:

‼️ IMPORTANT
Auto-reply has been disabled for this repository in the CodeRabbit settings. The CodeRabbit bot will not respond to your replies unless it is explicitly tagged.

• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
