Build

FalkorDB-rs is a Redis module: the Rust crates link against two native C libraries (GraphBLAS and RediSearch) that must be compiled and installed before cargo build will succeed.

1. First-time native dependency setup

Only needed once per machine/container (skip if cargo build already works).

./graphblas.sh    # clones, builds (static, PIC) and installs GraphBLAS v10.3.1 + LAGraph
./redisearch.sh   # clones and builds RediSearch (static) into redisearch/RediSearch/bin

If a script fails, read it before retrying by hand — graphblas.sh documents the exact cmake flags it uses (-DGRAPHBLAS_COMPACT=OFF, -DCMAKE_POSITION_INDEPENDENT_CODE=ON, static build, shared install prefix) and has a --skip-graphblas flag to reuse an already-installed libgraphblas.a while iterating on the LAGraph step.

2. Build

cargo build            # debug build -> target/debug/libfalkordb.{so,dylib}
cargo build --release  # release build -> target/release/libfalkordb.{so,dylib}

3. Format & lint

cargo fmt --all -- --check
CXX=clang++ cargo clippy --all-targets

• CXX=clang++ is required for clippy (and any build invoking the GraphBLAS FFI bindings under graph/src/graph/graphblas/, whose bindgen output is graphblas/mod.rs) — without it, clippy fails trying to compile the C shims.
• Format check uses the project's rustfmt.toml (vertical function-parameter layout). Run cargo fmt --all (no --check) to auto-fix.
• Run format + build + clippy together, in that order, for a full check — fail fast on formatting before spending time on a full compile.
• For a stricter, opt-in clippy pass (pedantic/nursery/cargo lints, plus an auto-fix mode) see the lint skill.

Notes

• CI (.github/workflows/rust-pr.yml) runs the same cargo fmt --all --check and CXX=clang++ cargo clippy --all-targets (pinned to a specific clang++ version in CI containers; any reasonably recent local clang++ works).
• Cross-platform release artifacts (Linux .so, macOS .dylib) and multi-arch Docker image publishing are handled entirely in CI — these need GH-hosted secrets/registries and are not meant to be reproduced locally.

If any step fails, report the errors clearly and help fix them.
