Module hugr_core::hugr::views

Read-only access into HUGR graphs and subgraphs.

Re-exports

• pub use self::petgraph::PetgraphWrapper;
• pub use descendants::DescendantsGraph;
• pub use sibling::SiblingGraph;
• pub use sibling_subgraph::SiblingSubgraph;

Modules

• descendants
  DescendantsGraph: view onto the subgraph of the HUGR starting from a root (all descendants at all depths).
• petgraph
  Implementations of petgraph’s traits for Hugr Region views.
• render
  Helper methods to compute the node/edge/port style when rendering a HUGR into dot or mermaid format.
• sibling
  SiblingGraph: view onto a sibling subgraph of the HUGR.
• sibling_subgraph
  Views for HUGR sibling subgraphs.

Structs

• RootChecked
  A view of the whole Hugr. (Just provides static checking of the type of the root node)

Traits

• HierarchyView
  A common trait for views of a HUGR hierarchical subgraph.
• HugrView
  A trait for inspecting HUGRs. For end users we intend this to be superseded by region-specific APIs.
• PortIterator
  Trait implementing methods on port iterators.
• RootTagged
  Trait for views that provides a guaranteed bound on the type of the root node.

Type Aliases

• IncomingNodePorts
  Wraps an iterator over (Node,Port) when the ports are known to be IncomingPorts
• IncomingPorts
  Wraps an iterator over Ports that are known to be IncomingPorts
• OutgoingNodePorts
  Wraps an iterator over (Node,Port) when the ports are known to be OutgoingPorts
• OutgoingPorts
  Wraps an iterator over Ports that are known to be OutgoingPorts
