Crate modelvault_core 

Embedded ModelVault database engine: append-only segments, versioned schema catalog, and last-write-wins row storage keyed by primary values.

Stable API (0.16+)

Prefer Database, prelude, and root type re-exports. Modules marked #[doc(hidden)] are format/engine internals and may change in minor releases.

Start with Database for open, register, insert, and get. Supporting types include Catalog, ScalarValue, FieldDef, and DbError. For a small import set, use prelude.
