oxigraph/lib/src/lib.rs

//! Oxigraph is a graph database library implementing the [SPARQL](https://www.w3.org/TR/sparql11-overview/) standard.
//!
//! Its goal is to provide a compliant, safe and fast graph on-disk database.
//! It also provides a set of utility functions for reading, writing, and processing RDF files.
//!
//! Oxigraph is in heavy development and SPARQL query evaluation has not been optimized yet.
//!
//! The disabled by default `"sophia"` feature provides [`sophia_api`](https://docs.rs/sophia_api/) traits implemention on Oxigraph terms and stores.
//!
//! Oxigraph also provides [a standalone HTTP server](https://crates.io/crates/oxigraph_server) based on this library.
//!
//!
//! The main entry point of Oxigraph is the [`Store`](store::Store) struct:
//!
//! ```
//! use oxigraph::store::Store;
//! use oxigraph::model::*;
//! use oxigraph::sparql::QueryResults;
//!
//! let store = Store::new()?;
//!
//! // insertion
//! let ex = NamedNode::new("http://example.com")?;
//! let quad = Quad::new(ex.clone(), ex.clone(), ex.clone(), GraphName::DefaultGraph);
//! store.insert(&quad)?;
//!
//! // quad filter
//! let results = store.quads_for_pattern(Some(ex.as_ref().into()), None, None, None).collect::<Result<Vec<Quad>,_>>()?;
//! assert_eq!(vec![quad], results);
//!
//! // SPARQL query
//! if let QueryResults::Solutions(mut solutions) =  store.query("SELECT ?s WHERE { ?s ?p ?o }")? {
//!     assert_eq!(solutions.next().unwrap()?.get("s"), Some(&ex.into()));
//! }
//! # Result::<_,Box<dyn std::error::Error>>::Ok(())
//! ```
