Struct Namespace

pub struct Namespace {
    pub name: String,
    pub iri: Uri<String>,
}

A Namespace represents a namespace IRI that can also be shown in abbreviated format, also known as “prefix”.

For instance, the namespace IRI http://www.w3.org/1999/02/22-rdf-syntax-ns# can also be shown (in RDF Turtle or SPARQL for instance) as rdf:. A “local name” such as “type” in such a namespace would look like http://www.w3.org/1999/02/22-rdf-syntax-ns#type or like rdf:type.

Fields

name: String

assumed to end with ‘:’

iri: Uri<String>

assumed to end with either ‘/’ or ‘#’

Implementations

impl Namespace

pub fn declare(name: &str, iri: &Uri<&str>) -> Result<Self, Error>

pub fn declare_iref_iri(name: &str, iri: &Iri) -> Result<Self, Error>

Variation of [declare] that takes an iref::Iri. We may want to move back to iref since iref 3 is now available which seems to have everything we need.

pub fn declare_from_str(name: &str, iri: &str) -> Result<Self, Error>

pub fn with_local_name(&self, name: &str) -> Result<Uri<String>, Error>

Return an identifier based on the current namespace IRI and the given local name within that namespace.

pub fn as_sparql_prefix(&self) -> String

pub fn as_turtle_prefix(&self) -> String

Trait Implementations

impl Clone for Namespace

fn clone(&self) -> Namespace

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Namespace

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

Formats the value using the given formatter.

impl Display for Namespace

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

Formats the value using the given formatter.

impl Hash for Namespace

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 Namespace

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