//! Oxigraph is a graph database implementing the [SPARQL](https://www.w3.org/TR/sparql11-overview/) standard.
//!
//! Its goal is to provide a compliant, safe and fast graph database.
//!
//! It currently provides three store implementations providing [SPARQL 1.1 query](https://www.w3.org/TR/sparql11-query/) capability:
//! * [`MemoryStore`](store/memory/struct.MemoryStore.html): a simple in memory implementation.
//! * [`RocksDbStore`](store/rocksdb/struct.RocksDbStore.html): a file system implementation based on the [RocksDB](https://rocksdb.org/) key-value store.
//!   It requires the `"rocksdb"` feature to be activated.
//!   The [clang](https://clang.llvm.org/) compiler needs to be installed to compile RocksDB.
//! * [`SledStore`](store/sled/struct.SledStore.html): another file system implementation based on the [Sled](https://sled.rs/) key-value store.
//!   It requires the `"sled"` feature to be activated.
//!   Sled is much faster to build than RockDB and does not require a C++ compiler.
//!   However, Sled is still in developpment, less tested and data load seems much slower than RocksDB.
//!
//! Oxigraph also provides a set of utility functions for reading, writing and processing RDF files.
//!
//! The disabled by default `"sophia"` feature provides [`sophia_api`](https://docs.rs/sophia_api/) traits implemention on Oxigraph terms and stores.
//!
//! Usage example with the [`MemoryStore`](store/memory/struct.MemoryStore.html):
//!
//! ```
//! use oxigraph::MemoryStore;
//! use oxigraph::model::*;
//! use oxigraph::sparql::{QueryOptions, QueryResults};
//!
//! let store = MemoryStore::new();
//!
//! // insertion
//! let ex = NamedNode::new("http://example.com")?;
//! let quad = Quad::new(ex.clone(), ex.clone(), ex.clone(), None);
//! store.insert(quad.clone());
//!
//! // quad filter
//! let results: Vec<Quad> = store.quads_for_pattern(Some(ex.as_ref().into()), None, None, None).collect();
//! assert_eq!(vec![quad], results);
//!
//! // SPARQL query
//! if let QueryResults::Solutions(mut solutions) =  store.query("SELECT ?s WHERE { ?s ?p ?o }", QueryOptions::default())? {
//!     assert_eq!(solutions.next().unwrap()?.get("s"), Some(&ex.into()));
//! }
//! # Result::<_,Box<dyn std::error::Error>>::Ok(())
//! ```
