If a particular feature of RocksDB is important to you, please let me know by opening an issue, and I'll prioritize it. ## Usage This binding is statically linked with a specific version of RocksDB. If you want to build it yourself, make sure you've also cloned the RocksDB and compression submodules: ```shell git submodule update --init --recursive ``` ## Compression Support By default, support for [Snappy](https://github.com/google/snappy), [LZ4](https://github.com/lz4/lz4), [Zstd](https://github.com/facebook/zstd), [Zlib](https://zlib.net), and [Bzip2](http://www.bzip.org) compression is enabled through crate features. If support for all of these compression algorithms is not needed, default features can be disabled and specific compression algorithms can be enabled. For example, to enable only LZ4 compression support, make these changes to your Cargo.toml: ```toml [dependencies.rocksdb] default-features = false features = ["lz4"] ``` ## Multithreaded ColumnFamily alternation RocksDB allows column families to be created and dropped from multiple threads concurrently, but this crate doesn't allow it by default for compatibility. If you need to modify column families concurrently, enable the crate feature `multi-threaded-cf`, which makes this binding's data structures use `RwLock` by default. Alternatively, you can directly create `DBWithThreadMode<MultiThreaded>` without enabling the crate feature. ## Switch between /MT or /MD run time library (Only for Windows) The feature `mt_static` will request the library to be built with [/MT](https://learn.microsoft.com/en-us/cpp/build/reference/md-mt-ld-use-run-time-library?view=msvc-170) flag, which results in library using the static version of the run-time library. *This can be useful in case there's a conflict in the dependecy tree between different run-time versions.* ## Switch between static and dynamic linking for bindgen (features `bindgen-static` and `bindgen-runtime`) The feature `bindgen-runtime` will enable the `runtime` feature of bindgen, which dynamically links to libclang. This is suitable for most platforms, and is enabled by default. The feature `bindgen-static` will enable the `static` feature of bindgen, which statically links to libclang. This is suitable for musllinux platforms, such as Alpine linux. To build on Alpine linux for example, make these changes to your Cargo.toml: ```toml [dependencies.rocksdb] default-features = false features = ["bindgen-static", "snappy", "lz4", "zstd", "zlib", "bzip2"] ``` Notice that `runtime` and `static` features are mutually exclusive, and won't compile if both enabled. ## LTO Enable the `lto` feature to enable link-time optimization. It will compile rocksdb with `-flto` flag. This feature is disabled by default. > [!IMPORTANT] > You must use clang as `CC`. Eg. `CC=/usr/bin/clang CXX=/usr/bin/clang++`. Clang llvm version must be the same as the one used by rust compiler. > On the rust side you should use `RUSTFLAGS="-Clinker-plugin-lto -Clinker=clang -Clink-arg=-fuse-ld=lld"`. Check the [Rust documentation](https://doc.rust-lang.org/rustc/linker-plugin-lto.html) for more information.
