SPARQL query results serialization formats.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

Xml

SPARQL Query Results XML Format

§

Json

SPARQL Query Results JSON Format

§

Csv

SPARQL Query Results CSV Format

§

Tsv

SPARQL Query Results TSV Format

Implementations§

§

impl QueryResultsFormat

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

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

use sparesults::QueryResultsFormat;

assert_eq!(
    QueryResultsFormat::Json.iri(),
    "http://www.w3.org/ns/formats/SPARQL_Results_JSON"
)

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

The format IANA media type.

use sparesults::QueryResultsFormat;

assert_eq!(
    QueryResultsFormat::Json.media_type(),
    "application/sparql-results+json"
)

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

The format IANA-registered file extension.

use sparesults::QueryResultsFormat;

assert_eq!(QueryResultsFormat::Json.file_extension(), "srj")

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

The format name.

use sparesults::QueryResultsFormat;

assert_eq!(QueryResultsFormat::Json.name(), "SPARQL Results in JSON")

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

Looks for a known format from a media type.

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

Example:

use sparesults::QueryResultsFormat;

assert_eq!(
    QueryResultsFormat::from_media_type("application/sparql-results+json; charset=utf-8"),
    Some(QueryResultsFormat::Json)
)

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

Looks for a known format from an extension.

It supports some aliases.

Example:

use sparesults::QueryResultsFormat;

assert_eq!(
    QueryResultsFormat::from_extension("json"),
    Some(QueryResultsFormat::Json)
)
