Implementations

impl<T, B, M> Properties<T, B, M>

impl<T: Eq + Hash, B: Eq + Hash, M> Properties<T, B, M>

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

Checks if the given property is associated to any object.

pub fn get<Q: IntoId<T, B>>(&self, prop: Q) -> Objects<'_, T, B, M>

Returns an iterator over all the objects associated to the given property.

pub fn get_any<Q: IntoId<T, B>>(
    &self,
    prop: Q
) -> Option<&IndexedObject<T, B, M>>

    value: IndexedObject<T, B, M>
)

Associate the given object to the node through the given property, unless it is already.

pub fn insert_all<Objects: IntoIterator<Item = IndexedObject<T, B, M>>>(
    &mut self,
    Meta: Meta<Id<T, B>, M>,
    values: Objects
)

    &mut self,
    Meta: Meta<Id<T, B>, M>,
    values: Objects
)

Associate all the given objects to the node through the given property, unless it is already.

The equivalence operator is used to remove equivalent objects.

    &mut self,
    prop: Meta<Id<T, B>, M>,
    values: Objects
)

    I: IntoIterator<Item = (Meta<Id<T, B>, M>, O)>,
    O: IntoIterator<Item = IndexedObject<T, B, M>>,
