Spargebra

Spargebra is a SPARQL parser.

It supports both SPARQL 1.1 Query and SPARQL 1.1 Update.

The emitted tree is based on SPARQL 1.1 Query Algebra objects.

The API entry point for SPARQL queries is the [Query] struct and the API entry point for SPARQL updates is the [Update] struct.

Support for 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.

Usage example:

use spargebra::Query;

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