Enum GraphFormat

#[non_exhaustive]
pub enum GraphFormat {
    NTriples,
    Turtle,
    RdfXml,
}

👎Deprecated since 0.4.0: use RdfFormat instead

RDF graph serialization formats.

This enumeration is non exhaustive. New formats like JSON-LD will 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.

NTriples

Implementations

impl GraphFormat

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

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

use oxigraph::io::GraphFormat;

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

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

The format IANA media type.

use oxigraph::io::GraphFormat;

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

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

The format IANA-registered file extension.

use oxigraph::io::GraphFormat;

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

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

Looks for a known format from a media type.

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

Example:

use oxigraph::io::GraphFormat;

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

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

Looks for a known format from an extension.

It supports some aliases.

Example:

use oxigraph::io::GraphFormat;

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

Trait Implementations

impl Clone for GraphFormat

fn clone(&self) -> GraphFormat

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GraphFormat

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<GraphFormat> for RdfFormat

fn from(format: GraphFormat) -> Self

Converts to this type from the input type.

impl From<GraphFormat> for RdfParser

fn from(format: GraphFormat) -> Self

Converts to this type from the input type.

impl From<GraphFormat> for RdfSerializer

fn from(format: GraphFormat) -> Self

Converts to this type from the input type.

impl Hash for GraphFormat

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for GraphFormat

fn eq(&self, other: &GraphFormat) -> 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.

impl TryFrom<DatasetFormat> for GraphFormat

fn try_from(value: DatasetFormat) -> Result<Self, Self::Error>

Attempts to find a graph format that is a subset of this DatasetFormat.

type Error = ()

The type returned in the event of a conversion error.

impl TryFrom<GraphFormat> for DatasetFormat

fn try_from(value: GraphFormat) -> Result<Self, Self::Error>

Attempts to find a dataset format that is a superset of this GraphFormat.

type Error = ()

The type returned in the event of a conversion error.

impl Copy for GraphFormat

impl Eq for GraphFormat

impl StructuralPartialEq for GraphFormat
