Enum RdfTerm 

pub enum RdfTerm {
    Iri(String),
    Literal {
        value: String,
        datatype: Option<String>,
        lang_tag: Option<String>,
    },
    BlankNode(String),
    Variable(String),
}

A single RDF term (IRI, literal, blank node, or variable).

Variants

Iri(String)

An IRI reference (angle-bracket form or prefixed name resolved to full IRI).

Literal

A plain or typed literal.

Fields

value: String

datatype: Option<String>

lang_tag: Option<String>

BlankNode(String)

A blank node with a locally-scoped label.

Variable(String)

A SPARQL variable (without the ? sigil).
