Expand description

Object.

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

Variants

`Value(Value<J, T>)`

Value object.

`Node(Node<J, T>)`

Node object.

`List(Vec<Indexed<Self>>)`

List object.

Implementations

source

impl<J: JsonHash, T: Id> Object<J, T>

source

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

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

source

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.

source

pub fn is_value(&self) -> bool

Tests if the object is a value.

source

pub fn as_value(&self) -> Option<&Value<J, T>>

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

source

pub fn into_value(self) -> Option<Value<J, T>>

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

source

pub fn is_node(&self) -> bool

Tests if the object is a node.

source

pub fn as_node(&self) -> Option<&Node<J, T>>

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

source

pub fn into_node(self) -> Option<Node<J, T>>

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

source

pub fn is_graph(&self) -> bool

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

source

pub fn is_list(&self) -> bool

Tests if the object is a list.

source

pub fn as_list(&self) -> Option<&[Indexed<Self>]>

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

source

pub fn into_list(self) -> Option<Vec<Indexed<Self>>>

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

source

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.

source

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

Get the value as a boolean, if it is.

source

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

Get the value as a number, if it is.

source

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

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