We need a lightweight, fast command-line tool written in Rust to parse and check food ingredient lists against a local database of E-numbers and halal-status keywords.

We are looking for an experienced freelancer to handle the following:
I need a simple Rust-based CLI tool. It should read an ingredient list from a text file or standard input, parse it, and cross-reference it against a local JSON file containing known Halal, Haram, and Mashbooh (doubtful) ingredients and E-numbers. The tool needs to output a clean, color-coded terminal report highlighting any flagged items. Keep the code simple, clean, and idiomatic. Please message me so we can discuss the exact JSON schema and your timeline.

Deliverables:
Deliver a completed Rust project (cargo-ready) with clean source code, a basic unit test suite for the matching logic, and a README with build instructions. Let's hop on a chat to finalize the requirements and talk about the details.

If you have relevant experience, please submit your proposal or reach out in chat.
