Hi @first-time-contributor! 🎉 Thanks for enhancing the Rust README with a quickstart guide—this is super helpful for new users!

The content looks great overall. Just one small fix: the Rust code snippet is missing syntax highlighting for the rust block. Please update it to use triple backticks with rust for proper formatting.

Refer to our CONTRIBUTING.md for more details. Let us know if you need help! 🚀

Reviewed - docs improvement, merging.

Thanks for this @MukundaKatta! This has a merge conflict after recent merges. Could you rebase on main and push again? Once clean, we'll merge it right away.

[imran-siddique]

Code is correct. Note: this PR conflicts with #1677 (both add Rust Cargo.toml content). Merge #1677 first, then rebase this PR. Will merge once #1677 lands.

[imran-siddique]

Blocked on #1677 (merge conflicts). Once #1677 is rebased and merged, this one will need a rebase too.

[MukundaKatta]

Rebased on latest main. The README conflict was additive — kept all the badges/intro from HEAD and added the new "Add to Your Project" section in the natural spot before "Workspace Commands". No content lost from either side.
