Rio

Rio is a low level library which provides conformant and fast parsers and formatters for RDF related file formats.

These libraries are going to be replaced by the oxttl and oxrdfxml libraries.

It currently provides N-Triples, N-Quads, Turtle, TriG and RDF/XML parsers and formatters.

It is split into multiple crates:

• rio_api provides common traits and data structures to be used in Rio parsers (Triple, TriplesParser, Iri...).
• rio_turtle provides conformant streaming parsers and formatters for Turtle, TriG, N-Triples and N-Quads. RDF-star syntaxes are also supported: Turtle-star, TriG-star, N-Triples-star and N-Quads-star.
• rio_xml provides a conformant streaming parser and a formatter for RDF/XML.

There is also the rio_testsuite crate that is used for testing Rio parsers against the W3C RDF tests to ensure their conformance. It provides both an executable for building implementation reports and integration test to quickly ensure that the parsers stay conformant. It is not designed to be used outside of Rio.
