alt Hacker NewsThis is super cool! I've always liked Rkyv (https://rkyv.org) but it requires Rust which can be a big lift for a small project. I see this supports binary data (`lite3_val_bytes`) which is great!

Thank you. Having a native bytes type is non-negotiable for any performance intensive application that cannot afford the overhead of base64 encoding. And yes, Rkyv also implements this idea of indexing serialized data. The main differences are:
1) Rkyv uses a binary tree vs Lite³ B-tree (B-trees are more cache and space efficient).
2) Rkyv is immutable once serialized. Lite³ allows for arbitrary mutations on serialized data.
3) Rkyv is Rust only. Lite³ is a 9.3 kB C library free of dependencies.
4) Rkyv as a custom binary format is not directly compatible with other formats. Lite³ can be directly converted to/from JSON.
I have not benchmarked Lite³ against Rust libraries, though it would be an interesting experiment.
