Rust CLI Task Manager
June 30, 2026 – Present
Built a lightweight CLI tool in Rust to manage tasks via a custom-binary format, focusing on memory safety and zero-cost abstractions. Created a custom storage engine using a .todo flat-file structure, opting for direct disk I/O over traditional database overhead to minimize latency and binary size. Implemented a high-speed indexing system using a separate .index file to map task IDs to byte offsets; this allows for O(1) random access and "seek-and-read" operations without needing to parse the entire dataset into RAM.
