Feedback and pull requests welcome! If a particular feature of RocksDB is important to you, please let me know by opening an issue, and I'll prioritize it.
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:
git submodule update --init --recursiveBy default, support for Snappy, LZ4, Zstd, Zlib, and Bzip2 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:
[dependencies.rocksdb]
default-features = false
features = ["lz4"]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.
The feature mt_static will request the library to be built with /MT
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.
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:
[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.
