Enum QueryResultsFormat

#[non_exhaustive]
pub enum QueryResultsFormat {
    Xml,
    Json,
    Csv,
    Tsv,
}

SPARQL query results serialization formats.

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.

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)
)

Trait Implementations

impl Clone for QueryResultsFormat

fn clone(&self) -> QueryResultsFormat

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QueryResultsFormat

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

Formats the value using the given formatter.

impl Display for QueryResultsFormat

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

Formats the value using the given formatter.

impl From<QueryResultsFormat> for QueryResultsParser

fn from(format: QueryResultsFormat) -> QueryResultsParser

Converts to this type from the input type.

impl From<QueryResultsFormat> for QueryResultsSerializer

fn from(format: QueryResultsFormat) -> QueryResultsSerializer

impl Hash for QueryResultsFormat

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

where __H: Hasher,

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 QueryResultsFormat

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