Struct DatasetParser

pub struct DatasetParser { /* private fields */ }

👎Deprecated since 0.4.0: use RdfParser instead

A parser for RDF dataset serialization formats.

It currently supports the following formats:

• N-Quads (DatasetFormat::NQuads)
• TriG (DatasetFormat::TriG)

use oxigraph::io::{DatasetFormat, DatasetParser};

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

let parser = DatasetParser::from_format(DatasetFormat::NQuads);
let quads = parser.read_quads(file.as_bytes()).collect::<Result<Vec<_>,_>>()?;

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

Implementations

impl DatasetParser

pub fn from_format(format: DatasetFormat) -> Self

Builds a parser for the given format.

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::{DatasetFormat, DatasetParser};

let file = "<g> { </s> </p> </o> }";

let parser =
    DatasetParser::from_format(DatasetFormat::TriG).with_base_iri("http://example.com")?;
let triples = parser
    .read_quads(file.as_bytes())
    .collect::<Result<Vec<_>, _>>()?;

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

pub fn read_quads<R: Read>(self, reader: R) -> QuadReader<R>

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