๐Ÿ‘ŽDeprecated since 0.4.0: use RdfParser instead
Expand description

Parsers for RDF graph serialization formats.

It currently supports the following formats:

use oxigraph::io::{GraphFormat, GraphParser};

let file = "<http://example.com/s> <http://example.com/p> <http://example.com/o> .";

let parser = GraphParser::from_format(GraphFormat::NTriples);
let triples = parser
    .read_triples(file.as_bytes())
    .collect::<Result<Vec<_>, _>>()?;

assert_eq!(triples.len(), 1);
assert_eq!(triples[0].subject.to_string(), "<http://example.com/s>");

Implementationsยง

Sourceยง

impl GraphParser

Source

pub fn from_format(format: GraphFormat) -> Self

Builds a parser for the given format.

Source

pub fn with_base_iri( self, base_iri: impl Into<String>, ) -> Result<Self, IriParseError>

Provides an IRI that could be used to resolve the file relative IRIs.

use oxigraph::io::{GraphFormat, GraphParser};

let file = "</s> </p> </o> .";

let parser =
    GraphParser::from_format(GraphFormat::Turtle).with_base_iri("http://example.com")?;
let triples = parser
    .read_triples(file.as_bytes())
    .collect::<Result<Vec<_>, _>>()?;

assert_eq!(triples.len(), 1);
assert_eq!(triples[0].subject.to_string(), "<http://example.com/s>");
Source

pub fn read_triples<R: Read>(self, reader: R) -> TripleReader<R> โ“˜

Executes the parsing itself on a Read implementation and returns an iterator of triples.
