Summary of Changes

Hello @Dargon789, 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 introduces a foundational continuous integration setup for Rust projects using CircleCI. By adding a ci_cargo.yml file, the project gains automated checks for code formatting and comprehensive test execution on every commit. This enhancement aims to improve code quality, catch regressions early, and streamline the development workflow by providing immediate feedback on changes.

Highlights

• New CI Configuration: A new CircleCI configuration file, ci_cargo.yml, has been added to the project to automate continuous integration processes for Rust code.
• Automated Build and Test Workflow: The configuration defines a build-and-test job that utilizes a Rust Docker image (cimg/rust:1.88.0) to ensure consistent build environments.
• Code Quality Checks: The CI pipeline now includes steps to check Rust code formatting using cargo fmt -- --check and to run all project tests with cargo test.
• Optimized Caching: Caching mechanisms for cargo dependencies (registry, git, target) have been implemented to significantly speed up subsequent CI runs by reusing previously built artifacts.

Hey there - I've reviewed your changes - here's some feedback:

• CircleCI looks for a single config file at .circleci/config.yml, so you’ll need to rename or merge ci_cargo.yml accordingly for it to be picked up.
• You’ve duplicated the “Check formatting” and “Run tests” steps—removing the redundant second set will streamline the workflow.

Code Review

This pull request introduces a new CircleCI workflow for running checks and tests on the Rust codebase. The configuration has a good foundation, including caching for Cargo dependencies to speed up builds. However, I've identified a couple of issues: there's a mismatch between the Rust version in the CI and the one specified in Cargo.toml, and there are duplicated build steps that should be removed for efficiency and clarity. Addressing these points will make the CI pipeline more robust and efficient.
