Enum RdfFormat

#[non_exhaustive]
pub enum RdfFormat {
    N3,
    NQuads,
    NTriples,
    RdfXml,
    TriG,
    Turtle,
}

RDF serialization formats.

This enumeration is non exhaustive. New formats like JSON-LD might be added in the future.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

N3

NQuads

N-Quads

Implementations

impl RdfFormat

pub const fn iri(self) -> &'static str

The format canonical IRI according to the Unique URIs for file formats registry.

use oxrdfio::RdfFormat;

assert_eq!(
    RdfFormat::NTriples.iri(),
    "http://www.w3.org/ns/formats/N-Triples"
)

pub const fn media_type(self) -> &'static str

The format IANA media type.

use oxrdfio::RdfFormat;

assert_eq!(RdfFormat::NTriples.media_type(), "application/n-triples")

pub const fn file_extension(self) -> &'static str

The format IANA-registered file extension.

use oxrdfio::RdfFormat;

assert_eq!(RdfFormat::NTriples.file_extension(), "nt")

pub const fn name(self) -> &'static str

The format name.

use oxrdfio::RdfFormat;

assert_eq!(RdfFormat::NTriples.name(), "N-Triples")

pub const fn supports_datasets(self) -> bool

Checks if the formats supports RDF datasets and not only RDF graphs.

use oxrdfio::RdfFormat;

assert_eq!(RdfFormat::NTriples.supports_datasets(), false);
assert_eq!(RdfFormat::NQuads.supports_datasets(), true);

pub const fn supports_rdf_star(self) -> bool

Checks if the formats supports RDF-star quoted triples.

use oxrdfio::RdfFormat;

assert_eq!(RdfFormat::NTriples.supports_rdf_star(), true);
assert_eq!(RdfFormat::RdfXml.supports_rdf_star(), false);

pub fn from_media_type(media_type: &str) -> Option<RdfFormat>

Looks for a known format from a media type.

It supports some media type aliases. For example, “application/xml” is going to return RdfFormat::RdfXml even if it is not its canonical media type.

Example:

use oxrdfio::RdfFormat;

assert_eq!(
    RdfFormat::from_media_type("text/turtle; charset=utf-8"),
    Some(RdfFormat::Turtle)
)

pub fn from_extension(extension: &str) -> Option<RdfFormat>

Looks for a known format from an extension.

It supports some aliases.

Example:

use oxrdfio::RdfFormat;

assert_eq!(RdfFormat::from_extension("nt"), Some(RdfFormat::NTriples))

impl PartialEq for RdfFormat

fn eq(&self, other: &RdfFormat) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
