Struct rdftk_core::model::data_set::name::GraphName

pub struct GraphName { /* fields omitted */ }

This type denotes the identifier for a graph in a data set; a graph name MUST be either an IRI or a blank node.

Implementations

impl GraphName

pub fn blank() -> Self

Construct a new graph name, as a blank node with a randomly assigned name.

pub fn blank_ref() -> GraphNameRef

Construct a new graph name reference, as a blank node with a randomly assigned name.

pub fn blank_named(name: &str) -> Self

Construct a new graph name, as a blank node with the specified name.

pub fn named(name: IRIRef) -> Self

Construct a new graph name, with an IRI naming a resource.

pub fn named_ref(name: IRIRef) -> GraphNameRef

Construct a new graph name reference, with an IRI naming a resource.

pub fn is_blank(&self) -> bool

Return true if this graph name is a blank node, else false.

pub fn as_blank(&self) -> Option<&String>

Return a blank node string, if self.is_blank(), else None.

pub fn is_iri(&self) -> bool

Return true if this graph name is an IRI, else false.

pub fn as_iri(&self) -> Option<&IRIRef>

Return a named node IRI, if self.is_iri(), else None.
