    Node {
        id: Option<&'a Id<T, B>>,
    },
    Graph {
        id: Option<&'a Id<T, B>>,

    Json,
    List(&'a [ValueKind<'a, T, B>]),
    EmptyArray,
}

Kind of a value described by a ValueHint.

Each variant stands for one shape of expanded JSON-LD and carries exactly the parts of it that IRI compaction reads.

Variants

Node

A node object that is not a graph object, such as a node reference ({"@id": ...}), together with its @id, if any.

When the @id compacts to a term whose IRI mapping is that same @id, term selection prefers @vocab-typed terms over @id-typed ones.

Fields

id: Option<&'a Id<T, B>>

The node’s @id.

Graph

A graph object (a node object whose only entries are @graph and optionally @id and @index), together with its @id, if any.

Fields

id: Option<&'a Id<T, B>>

The graph’s @id.

Literal

A value object whose @value is a string, number, boolean or null, with no @language and no @direction.

Fields

datatype: Option<&'a T>

The value’s @type IRI, if it has one.

LangString

A value object holding a string with a @language, a @direction, or both.

Fields

language: Option<&'a LenientLangTag>

The value’s @language.

direction: Option<Direction>

The value’s @direction.

Json

A value object of type @json.

List(&'a [ValueKind<'a, T, B>])

A list object, with the kinds of its items in order.

Only whether each item is a value object, and its type, language and direction if it is, take part in term selection; @index entries of the items do not.

EmptyArray

The empty array an expanded property holds when it has no values.

Selects the term an @id-less node object would.
