Mutable dataset.

Required Associated Types

type GraphsMut<'a>: Iterator<Item = (Option<&'a Self::GraphLabel>, &'a mut Self::Graph)> where Self: 'a

Iterator over mutable graphs.

Required Methods

fn graph_mut( &mut self, id: Option<&Self::GraphLabel>, ) -> Option<&mut Self::Graph>

Get the given graph mutably.

Use the input None to get the default graph.

Note to implementors: the default graph should always exists.

fn graphs_mut(&mut self) -> Self::GraphsMut<'_>

Returns an iterator over the (mutable) graphs of the dataset.

fn insert_graph( &mut self, id: Self::GraphLabel, graph: Self::Graph, ) -> Option<Self::Graph>

Insert a graph in the dataset with the given name.

If a graph with the given name already exists, it is replaced and the previous graph definition is returned.

fn insert( &mut self, quad: Quad<Self::Subject, Self::Predicate, Self::Object, Self::GraphLabel>, ) -> bool

Insert a quad in the dataset.

fn remove( &mut self, quad: Quad<&Self::Subject, &Self::Predicate, &Self::Object, &Self::GraphLabel>, )

Remove a quad from the dataset.

fn absorb<D: SizedDataset<Subject = Self::Subject, Predicate = Self::Predicate, Object = Self::Object, GraphLabel = Self::GraphLabel>>( &mut self, other: D, )

where D::Graph: SizedGraph,

Absorb the given other dataset.

Adds all the quads of other in the dataset.

Provided Methods

fn default_graph_mut(&mut self) -> &mut Self::Graph

Get the default graph mutably.

Note to implementors: the default graph should always exists.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
