Spargebra is a [SPARQL](https://www.w3.org/TR/sparql11-overview/) parser.

It supports [SPARQL 1.1 Query](https://www.w3.org/TR/sparql11-query/) and [SPARQL 1.1 Update](https://www.w3.org/TR/sparql11-update/).

Support for [SPARQL-star](https://w3c.github.io/rdf-star/cg-spec/#sparql-star) is also available behind the `rdf-star` feature.

This crate is intended to be a building piece for SPARQL implementations in Rust like [Oxigraph](https://oxigraph.org).

Usage example:

```rust
use spargebra::Query;

let query_str = "SELECT ?s ?p ?o WHERE { ?s ?p ?o . }";
let mut query = Query::parse(query_str, None)?;
assert_eq!(query.to_string(), query_str);
```
