Enum nquads_syntax::Subject

pub enum Subject<I = IriBuf, B = BlankIdBuf> {
    Blank(B),
    Iri(I),
}

RDF Subject.

Either a blank node identifier or an IRI.

Hash implementation

It is guaranteed that the Hash implementation of Subject is transparent, meaning that the hash of Term::Blank(id) the same as id and the hash of Subject::Iri(iri) is the same as iri.

Variants

Blank(B)

Blank node identifier.

Iri(I)

IRI.
