Struct oxigraph::model::NamedNodeRef

pub struct NamedNodeRef<'a> { /* fields omitted */ }

A borrowed RDF IRI

The default string formatter is returning an N-Triples, Turtle and SPARQL compatible representation:

use oxigraph::model::NamedNodeRef;

assert_eq!(
    "<http://example.com/foo>",
    NamedNodeRef::new("http://example.com/foo")?.to_string()
);

Implementations

impl<'a> NamedNodeRef<'a>

pub fn new(iri: &'a str) -> Result<Self, IriParseError>

Builds and validate an RDF IRI

pub const fn new_unchecked(iri: &'a str) -> Self

Builds an RDF IRI from a string.

It is the caller's responsibility to ensure that iri is a valid IRI.

parse is a safe version of this constructor and should be used for untrusted data.

pub const fn as_str(self) -> &'a str

pub fn into_owned(self) -> NamedNode
