Struct PrefixMapping

pub struct PrefixMapping { /* private fields */ }

Implementation of a mapping from a prefix Name to an Iri. Prefix mappings are commonly used in the serialization of graphs.

Implementations

impl PrefixMapping

pub fn common() -> Self

pub fn with_default(self, iri: Iri) -> Self

where Self: Sized,

Construct a new mapping instance with the provided default namespace.

pub fn with_dc_terms(self) -> Self

where Self: Sized,

Include the common “dc::terms” mapping.

pub fn with_dc_elements(self) -> Self

where Self: Sized,

Include the common “dc::elements” mapping.

pub fn with_foaf(self) -> Self

where Self: Sized,

Include the common “foaf” mapping.

pub fn with_owl(self) -> Self

where Self: Sized,

Include the common “owl” mapping.

pub fn with_rdf(self) -> Self

where Self: Sized,

Include the common “rdf” mapping.

pub fn with_rdfs(self) -> Self

where Self: Sized,

Include the common “rdfs” mapping.

pub fn with_xsd(self) -> Self

where Self: Sized,

Include the common “xsd” (XML Schema Data types) mapping.

pub fn with_skos(self) -> Self

where Self: Sized,

Include the common “skos” mapping.

pub fn with(self, prefix: Name, iri: Iri) -> Self

where Self: Sized,

pub fn is_empty(&self) -> bool

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

pub fn len(&self) -> usize

Return the number of mappings in this instance.

pub fn get_default_namespace(&self) -> Option<&Iri>

Get the default namespace mapping, if present.

pub fn set_default_namespace(&mut self, iri: Iri)

Set the default namespace mapping.

pub fn remove_default_namespace(&mut self)

pub fn get_namespace(&self, prefix: &Name) -> Option<&Iri>

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

pub fn get_prefix(&self, namespace: &Iri) -> Option<&Option<Name>>

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

pub fn mappings<'a>( &'a self, ) -> Box<dyn Iterator<Item = (&'a Option<Name>, &'a Iri)> + 'a>

Return an iterator over the contained mappings.

pub fn insert(&mut self, prefix: Name, iri: Iri)

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

pub fn insert_owl(&mut self)

pub fn insert_rdf(&mut self)

pub fn insert_rdfs(&mut self)

pub fn insert_xsd(&mut self)

pub fn insert_foaf(&mut self)

pub fn insert_dc_elements(&mut self)

pub fn insert_dc_terms(&mut self)

pub fn insert_skos(&mut self)

pub fn insert_skos_xl(&mut self)

pub fn insert_skos_iso(&mut self)

pub fn remove(&mut self, prefix: &Name)

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

pub fn clear(&mut self)

Remove all mappings from this instance.

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

Expand a qname into an Iri, if possible.

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

Compress an Iri into a qname, if possible.

Trait Implementations

impl Clone for PrefixMapping

fn clone(&self) -> PrefixMapping

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrefixMapping

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

Formats the value using the given formatter.

impl Default for PrefixMapping

fn default() -> PrefixMapping

Returns the “default value” for a type.

impl PartialEq for PrefixMapping

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