This repository is a Rust SDK/framework for building Redis modules, not an end-user application or data/research project. The workspace is organized as a library crate (`redis-module`) plus proc-macro helper crates (`redismodule-rs-macros`, `redismodule-rs-macros-internals`) that wrap the Redis Modules C API. Build code consumes vendored `redismodule.h` through `bindgen`, and the public API provides safe `Context`, `RedisKey`, `RedisString`, `RedisValue`, `RedisModuleIO`, configuration, key cursors, timers, blocking clients, thread-safe contexts, and command/info-handler registration. `redis_module!` and `#[command]` are the main module entry points; the included examples are small runnable modules, and integration tests spawn real `redis-server` processes to exercise them. Architecturally, the crate uses an unsafe FFI layer (`src/raw.rs`) underneath higher-level modules (`src/context/`, `src/key.rs`, `src/configuration.rs`, `src/io.rs`), and uses `linkme::distributed_slice` plus procedural macros to collect command, event, info, and defrag handlers. API-version compatibility is handled by feature flags (`min-redis-compatibility-version-6-0` through `8-0`) with a manual mapping table in `redismodule-rs-macros-internals/src/api_versions.rs`. The vendored C header includes Redis Labs / BigRedis extensions, reflecting production use inside Redis Enterprise modules. External build dependencies include `bindgen`, `cc`, libclang, and a Redis-compatible server for tests. The codebase is well structured for a low-level FFI SDK and contains several genuinely reusable patterns, but it has meaningful caveats: generated bindings are not committed, `bindgen` is pinned to an old version, the manual API-version table must be kept in sync as Redis evolves, and the FFI layer is necessarily large and unsafe. Overall it is an actively maintained, professional-quality SDK with a few deprecated APIs and some fragility around version-gated calls.
