Enum JsonLdObject 

pub enum JsonLdObject {
    Value(JsonLdValue),
    List(JsonLdList),
    Node(Box<JsonLdNode>),
}

Object.

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

You can get a JsonLdObject by expanding a JSON-LD document using the expansion algorithm.

Variants

Value(JsonLdValue)

Value object.

List(JsonLdList)

List object.

Node(Box<JsonLdNode>)

Node object.

Implementations

impl JsonLdObject

pub fn null() -> Self

Creates a null value object.

pub fn node(n: JsonLdNode) -> Self

Creates a new node object from a node.

pub fn id(&self) -> Option<&JsonLdLenient<Id>>

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

pub fn types(&self) -> JsonLdObjectTypes<'_>

Returns an iterator over the types of the 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 as_value(&self) -> Option<&JsonLdValue>

Returns this object as a value, if it is one.

pub fn as_value_mut(&mut self) -> Option<&mut JsonLdValue>

Returns this object as a mutable value, if it is one.

pub fn into_value(self) -> Option<JsonLdValue>

Converts this object as a value, if it is one.

pub fn is_node(&self) -> bool

Tests if the object is a node.

pub fn as_node(&self) -> Option<&JsonLdNode>

Returns this object as a node, if it is one.

pub fn as_node_mut(&mut self) -> Option<&mut JsonLdNode>

Returns this object as a mutable node, if it is one.

pub fn into_node(self) -> Option<JsonLdNode>

Converts this object into a node, if it is one.

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_list(&self) -> Option<&JsonLdList>

Returns this object as a list, if it is one.

pub fn as_list_mut(&mut self) -> Option<&mut JsonLdList>

Returns this object as a mutable list, if it is one.

pub fn into_list(self) -> Option<JsonLdList>

Converts this object into a list, if it is one.

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<&JsonNumber>

Get the value as a number, if it is.

pub fn language(&self) -> Option<JsonLdLenient<&LangTag>>

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

pub fn equivalent(&self, other: &Self) -> bool

Equivalence operator.

Equivalence is different from equality for anonymous objects: List objects and anonymous node objects have an implicit unlabeled blank nodes and thus never equivalent.

pub fn entries(&self) -> Entries<'_>

Returns an iterator over the entries of JSON representation of the object.
