Struct json_ld::object::node::reverse_properties::ReverseProperties

pub struct ReverseProperties<J: JsonHash, T: Id>(_);

Reverse properties of a node object, and their associated nodes.

Implementations

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

pub fn len(&self) -> usize

Returns the number of reverse properties.

pub fn is_empty(&self) -> bool

Checks if there are no defined reverse properties.

pub fn contains<Q: ToReference<T>>(&self, prop: Q) -> bool

Checks if the given reverse property is associated to any node.

pub fn get<'a, Q: ToReference<T>>(&self, prop: Q) -> Nodes<'_, J, T> where
    T: 'a, 

Returns an iterator over all the nodes associated to the given reverse property.

pub fn get_any<'a, Q: ToReference<T>>(
    &self,
    prop: Q
) -> Option<&Indexed<Node<J, T>>> where
    T: 'a, 

Get one of the nodes associated to the given reverse property.

If multiple nodes are found, there are no guaranties on which node will be returned.

pub fn insert(&mut self, prop: Reference<T>, value: Indexed<Node<J, T>>)

Associate the given node to the given reverse property.

pub fn insert_all<Objects: Iterator<Item = Indexed<Node<J, T>>>>(
    &mut self,
    prop: Reference<T>,
    values: Objects
)

Associate all the given nodes to the given reverse property.

pub fn iter(&self) -> Iter<'_, J, T>

Returns an iterator over the reverse properties and their associated nodes.

pub fn iter_mut(&mut self) -> IterMut<'_, J, T>

Returns an iterator over the reverse properties with a mutable reference to their associated nodes.

Trait Implementations

impl<J: JsonHash, T: Id> Hash for ReverseProperties<J, T>

fn hash<H: Hasher>(&self, h: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl<'a, J: JsonHash, T: Id> IntoIterator for &'a ReverseProperties<J, T>

type Item = ReverseBindingRef<'a, J, T>

impl<J: PartialEq + JsonHash, T: PartialEq + Id> PartialEq<ReverseProperties<J, T>> for ReverseProperties<J, T>

fn eq(&self, other: &ReverseProperties<J, T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ReverseProperties<J, T>) -> bool

This method tests for !=.
