Enum json_ld::object::Object

pub enum Object<T: Id = IriBuf> {
    Value(Value<T>),
    Node(Node<T>),
    List(Vec<Indexed<Object<T>>>),
}

Object.

JSON-LD connects together multiple kinds of data objects. Objects may be nodes, values or lists of objects.

Variants

Value(Value<T>)

Value object.

Tuple Fields of Value

0: Value<T>

Node(Node<T>)

Node object.

Tuple Fields of Node

0: Node<T>

List(Vec<Indexed<Object<T>>>)

List object.

Tuple Fields of List

0: Vec<Indexed<Object<T>>>

Implementations

impl<T: Id> Object<T>

pub fn id(&self) -> Option<&Reference<T>>

Identifier of the object, if it is a node object.

pub fn as_iri(&self) -> Option<Iri<'_>>

Identifier of the object as an IRI.

If the object is a node identified by an IRI, returns this IRI. Returns None otherwise.

pub fn is_value(&self) -> bool

Tests if the object is a value.

pub fn is_node(&self) -> bool

Tests if the object is a node.

pub fn is_graph(&self) -> bool

Tests if the object is a graph object (a node with a @graph field).

pub fn is_list(&self) -> bool

Tests if the object is a list.

pub fn as_str(&self) -> Option<&str>

Get the object as a string.

If the object is a value that is a string, returns this string. If the object is a node that is identified, returns the identifier as a string. Returns None otherwise.

pub fn as_bool(&self) -> Option<bool>

Get the value as a boolean, if it is.

pub fn as_number(&self) -> Option<Number>

Get the value as a number, if it is.

pub fn language(&self) -> Option<LanguageTag<'_>>

If the objat is a language-tagged value, Return its associated language.
