Struct Environment 

pub struct Environment<'n, N: Vocabulary, G> { /* private fields */ }

Vocabulary and blank node generator used while flattening.

Implementations

impl<'n, N: Vocabulary, G> Environment<'n, N, G>

pub fn new(vocabulary: &'n mut N, generator: G) -> Self

Creates a new Environment.

impl<V, G: LocalGenerator> Environment<'_, V, G>

where V: VocabularyMut + Vocabulary, V::Iri: Clone, V::BlankId: Clone + Hash + Eq,

pub fn assign( &mut self, blank_id: V::BlankId, ) -> Result<ValidId<V::Iri, V::BlankId>, GeneratedIdError>

Returns the identifier this blank node was relabelled to, generating one on first sight.

Errors

Returns an error when the generator runs out of identifiers.

pub fn assign_node_id( &mut self, r: Option<&VocabularyId<V>>, ) -> Result<Id<V::Iri, V::BlankId>, GeneratedIdError>

Returns the identifier of a node, generating a blank one when the node is anonymous.

Errors

Returns an error when the generator runs out of identifiers.

pub fn next_id( &mut self, ) -> Result<ValidId<V::Iri, V::BlankId>, GeneratedIdError>

Generates a fresh blank node identifier.

Errors

Returns an error when the generator runs out of identifiers.
