Crate oxilite 

oxilite: an Oxigraph-compatible RDF database and SPARQL engine that uses SQLite as its storage engine.

The module layout mirrors Oxigraph (model, io, sparql, store), so code written for oxigraph::store::Store works with oxilite::store::Store after changing the crate name. AsyncStore offers the same API over async backends such as Cloudflare D1.

use oxilite::model::*;
use oxilite::sparql::QueryResults;
use oxilite::store::Store;

let store = Store::new()?;
let ex = NamedNodeRef::new("http://example.com")?;
store.insert(QuadRef::new(ex, ex, ex, GraphNameRef::DefaultGraph))?;
if let QueryResults::Solutions(mut solutions) = store.query("SELECT ?s WHERE { ?s ?p ?o }")? {
    assert_eq!(solutions.next().unwrap()?.get("s"), Some(&ex.into_owned().into()));
}

Re-exports

pub use oxilite_core as core;

Modules

blocking

The same Store as store::Store (blocking API).

functions

Host functions: application code callable from SPARQL, Cypher and Datalog (Store::register_function).

io

RDF parsers and serializers (re-export of oxrdfio, like oxigraph::io).

model

RDF data model (re-export of oxrdf, like oxigraph::model).

rusqlite

The in-process SQLite backend (bundled SQLite, UDFs).

schema

The schema registry: ontologies and shapes graphs declared as such in the system graph <oxilite:schema>, which graphs they apply to, and the compiled shape index they feed.

sparql

SPARQL types (like oxigraph::sparql).

store

The blocking store, a drop-in replacement for oxigraph::store::Store.

vector

Vector indexes over embedding literals and nearest-neighbour search (Store::create_vector_index, Store::vector_search; backends with vector functions: Turso).

version

Optional versioning: the store clock, the immutable change log and time travel (see StoreOptions::versioning, Store::set_versioning, QueryOptions::as_of).

Structs

AsyncStore

An RDF dataset in a SQLite-compatible engine reached asynchronously.

Capabilities

What a backend can do. The compiler adapts SQL generation to it.

QueryOptions

Per-query options.

RegisteredGraph

A registry entry.

Registration

What is recorded about a registered graph, besides its name and role.

StoreOptions

Options chosen when a store is created.

Enums

Error

Errors raised by oxilite.

Traits

AsyncBackend

A backend that runs requests asynchronously (D1, network engines).

SyncBackend

A backend that runs requests synchronously.

Type Aliases

Result

Result alias used across oxilite.
