//! OxRDF is a simple library providing datastructures encoding [RDF 1.1 concepts](https://www.w3.org/TR/rdf11-concepts/).
//!
//! This crate is intended to be a basic building block of other crates like [Oxigraph](https://crates.io/crates/oxigraph) or [Spargebra](https://crates.io/crates/spargebra).
//!
//! Inspired by [RDF/JS](https://rdf.js.org/data-model-spec/) and [Apache Commons RDF](http://commons.apache.org/proper/commons-rdf/).
//!
//! Usage example:
//!
//! Usage example:
//! ```
//! use oxrdf::*;
//!
//! let mut graph = Graph::default();
//!
//! // insertion
//! let ex = NamedNodeRef::new("http://example.com")?;
//! let triple = TripleRef::new(ex, ex, ex);
//! graph.insert(triple);
//!
//! // simple filter
//! let results: Vec<_> = graph.triples_for_subject(ex).collect();
//! assert_eq!(vec![triple], results);
//! # Result::<_,Box<dyn std::error::Error>>::Ok(())
