Enum rio_api::model::Term

pub enum Term<'a> {
    NamedNode(NamedNode<'a>),
    BlankNode(BlankNode<'a>),
    Literal(Literal<'a>),
    Triple(&'a Triple<'a>),
}

An RDF term.

It is the union of IRIs, blank nodes and literals.

The default string formatter is returning an N-Triples, Turtle and SPARQL compatible representation.
