Prefix mappings are used in the serialization of graphs.

Required methods

fn is_empty(&self) -> bool

Returns true if there are no mappings in this instance, else false.

fn len(&self) -> usize

Return the number of mappings in this instance.

fn set_default_namespace(&mut self, iri: IRIRef) -> &mut Self where
    Self: Sized, 

Set the default namespace mapping.

fn get_namespace(&self, prefix: &Prefix) -> Option<&IRIRef>

Get the namespace IRI associated with this provided prefix, if present.

fn get_prefix(&self, namespace: &IRIRef) -> Option<&Prefix>

Get the prefix associated with this provided namespace URI, if present.

fn prefixes(&self) -> Vec<&Prefix>

Return the set of prefixes in this mapping instance.

fn insert(&mut self, prefix: &str, iri: IRIRef) -> &mut Self where
    Self: Sized, 

Insert a mapping from the prefix string to the namespace IRI.

fn remove(&mut self, prefix: &Prefix)

Remove a mapping for the provided prefix. This operation has no effect if no mapping is present.

fn clear(&mut self)

Remove all mappings from this instance.

fn expand(&self, qname: &QName) -> Option<IRIRef>

Expand a qname into an IRI, if possible.

fn compress(&self, iri: &IRIRef) -> Option<QName>

Compress an IRI into a qname, if possible.
