Struct NamedNode

Source
pub struct NamedNode { /* private fields */ }
Expand description

An owned RDF IRI.

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

use oxrdf::NamedNode;

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

Implementations§

Source§

impl NamedNode

Source

pub fn new(iri: impl Into<String>) -> Result<NamedNode, IriParseError>

Builds and validate an RDF IRI.

Source

pub fn new_unchecked(iri: impl Into<String>) -> NamedNode

Builds an RDF IRI from a string.

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

NamedNode::new() is a safe version of this constructor and should be used for untrusted data.
