Enum LiteralTypeRef 

pub enum LiteralTypeRef<'a> {
    Any(DatatypeRef<'a>),
    LangString(&'a LangTag),
    DirLangString {
        tag: &'a LangTag,
        direction: Direction,
    },
}

RDF literal type reference.

Read-only counterpart of LiteralType. The Any variant wraps a validated DatatypeRef so safe construction cannot produce a LiteralTypeRef::Any(rdf:langString) or LiteralTypeRef::Any(rdf:dirLangString).

Variants

Any(DatatypeRef<'a>)

Typed literal datatype.

LangString(&'a LangTag)

Language-tagged literal with no base direction.

DirLangString

Directional language-tagged literal (RDF 1.2).

Fields

tag: &'a LangTag

Language tag.

direction: Direction

Base direction.
