Enum json_ld::Reference

pub enum Reference<T: AsIri = IriBuf> {
    Id(T),
    Blank(BlankId),
    Invalid(String),
}

Node reference.

Used to reference a node across a document or to a remote document. It can be an identifier (IRI) or a blank node identifier for local blank nodes.

Variants

Id(T)

Node identifier, essentially an IRI.

Tuple Fields of Id

0: T

Blank(BlankId)

Blank node identifier.

Tuple Fields of Blank

0: BlankId

Invalid(String)

Invalid reference.

Tuple Fields of Invalid

0: String

Implementations

impl<T: AsIri> Reference<T>

pub fn is_valid(&self) -> bool

Checks if this is a valid reference.

Returns true is this reference is a node identifier or a blank node identifier, false otherwise.

pub fn as_str(&self) -> &str

Get a string representation of the reference.

This will either return a string slice of an IRI, or a blank node identifier.

pub fn as_iri(&self) -> Option<Iri<'_>>

If the renference is a node identifier, returns the node IRI.

Returns None if it is a blank node reference.

pub fn into_term(self) -> Term<T>
