BuffDB is a Rust library to simplify multi-plexing on edge devices

BuffDB is an experimental software project designed as a lightweight, high-performance persistence layer for gRPC, developed in Rust. It is particularly useful in environments with limited bandwidth and critical performance needs, utilizing Protobuf as its messaging format. BuffDB supports multiple backends, including SQLite, DuckDB, and RocksDB, with the SQLite backend offering full support and the others providing partial support. The binary size is under 2 MiB when using SQLite with dynamic linking. BuffDB allows interaction through auto-generated TypeScript code from the protobuf definition, facilitating multi-language support. To integrate BuffDB into a Rust project, users can execute `cargo add buffdb`. The server can be started after cloning the repository with the command `cargo run --all-features -- run`, which will launch it on `[::1]:50051`. BuffDB also features a command line interface for managing key-value pairs and blob data, with commands for retrieving and setting values, as well as storing files. It is particularly suited for applications requiring offline data access, such as note-taking apps, games, and IoT device management.
