Core functions that should (almost-)always be implemented by pointing at the underlying graph.

Required Methods

fn single_layer(&self, layer_ids: &LayerIds) -> Option<usize>

Return the id of the single layer if layer_ids reduces to a graph with a single layer, else None

fn core_edges(&self) -> EdgesStorage

fn get_layer_names_from_ids( &self, layer_ids: &LayerIds, ) -> Box<dyn Iterator<Item = ArcStr> + Send + Sync>

Get the layer name for a given id

fn get_all_node_types(&self) -> Vec<ArcStr>

Get all node types

fn node_id(&self, v: VID) -> GID

Returns the external ID for a node

fn node_name(&self, v: VID) -> String

fn node_type_id(&self, v: VID) -> usize

Returns the type id of a node

fn internalise_node(&self, v: NodeRef<'_>) -> Option<VID>

Gets the internal reference for an external node reference and keeps internal references unchanged.

fn internalise_node_unchecked(&self, v: NodeRef<'_>) -> VID

Gets the internal reference for an external node reference and keeps internal references unchanged. Assumes node exists!

fn node_metadata(&self, v: VID, id: usize) -> Option<Prop>

Gets a static property of a given node given the name and node reference.

Arguments

• v - A reference to the node for which the property is being queried.
• name - The name of the property.

Returns

The property value if it exists.

fn node_metadata_ids( &self, v: VID, ) -> Box<dyn Iterator<Item = usize> + Send + Sync + '_>

Gets the keys of metadata of a given node

Arguments

• v - A reference to the node for which the property is being queried.

Returns

The keys of the metadata.

fn temporal_node_prop_ids(&self, v: VID) -> Box<dyn Iterator<Item = usize> + '_>

Returns a vector of all ids of temporal properties within the given node

Arguments

• v - A reference to the node for which to retrieve the names.

Returns

The ids of the temporal properties

Dyn Compatibility

This trait is dyn compatible.

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