# oxilite-rusqlite [](https://crates.io/crates/oxilite-rusqlite) [](https://docs.rs/oxilite-rusqlite) [](https://github.com/Volland/oxilite#license) **In-process SQLite backend for oxilite**, built on rusqlite with a bundled SQLite. It is the default backend of the [`oxilite`](https://crates.io/crates/oxilite) store. **[Website](https://oxilitedb.com)** · [API docs](https://docs.rs/oxilite-rusqlite) · **[Guide and architecture](https://github.com/Volland/oxilite#readme)** · [Changelog and issues](https://github.com/Volland/oxilite/issues) It also registers oxilite's SQL functions (SPARQL regular expressions, `REPLACE`, hashes, `ENCODE_FOR_URI`) and Unicode-aware `upper` / `lower`, so **every SPARQL function compiles to SQL** on this backend. ## Usage You normally get it through `oxilite` (feature `rusqlite`, on by default): ```rust let store = oxilite::store::Store::open("data.sqlite")?; // RusqliteBackend underneath ``` To build the backend yourself, for example over an existing `rusqlite::Connection`: ```rust use oxilite::store::Store; use oxilite_rusqlite::RusqliteBackend; let backend = RusqliteBackend::open("data.sqlite")?; // or ::memory(), ::open_read_only(path) // let backend = RusqliteBackend::from_connection(conn)?; // share your own connection let store = Store::with_backend(backend)?; ``` Atomic requests run in one transaction. The connection uses WAL mode for file databases. ## The oxilite family oxilite is an Oxigraph-compatible RDF database and SPARQL 1.1 engine that stores its data in SQLite, so it runs anywhere SQLite runs: in-process, on a system or vendor `libsqlite3`, on Cloudflare D1 and in Durable Objects. The same data can be queried with SPARQL and openCypher, reasoned over with RDFS / OWL, and validated with SHACL and ShEx.
