leveldb-rs
A fully compatible implementation of LevelDB in Rust. (any incompatibility is a bug!)
The implementation is very close to the original; often, you can see the same algorithm translated 1:1, and class (struct) and method names are similar or the same.
NOTE: I do not endorse using this library for any data that you care about. I do care, however, about bug reports.
Status
Working well, with a few rare bugs (see issues).
Goals
Some of the goals of this implementation are
- As few copies of data as possible; most of the time, slices of bytes (
&[u8]
) are used. Owned memory is represented asVec<u8>
(and then possibly borrowed as slice). Zero-copy is not always possible, though, and sometimes simplicity is favored. - Correctness -- self-checking implementation, good test coverage, etc. Just like the original implementation.
- Clarity; commented code, clear structure (hopefully doing a better job than the original implementation).
- Coming close-ish to the original implementation; clarifying the translation of typical C++ constructs to Rust, and doing a better job at helping understand the internals.
