Struct NodeRegistry 

pub struct NodeRegistry { /* private fields */ }

Registry for node kinds.

Implementations

impl NodeRegistry

pub fn plan_canonicalize_kinds(&self, graph: &Graph) -> CanonicalizeKindsPlan

Plans a transaction that rewrites aliased node kinds to their canonical kind.

pub fn plan_migrate_nodes(&self, graph: &Graph) -> MigrateNodesPlan

Plans a transaction that upgrades node payloads to the latest registered kind version.

This plan is intentionally best-effort:

• missing schema -> recorded as a report entry, no edits are produced
• missing migrator -> recorded as a report entry, no edits are produced
• migrator errors -> recorded as a report entry, no edits are produced for that node

The returned transaction may also include SetNodeKind ops for aliased kinds.

impl NodeRegistry

pub fn new() -> Self

Creates an empty registry.

pub fn register(&mut self, schema: NodeSchema)

Registers a schema.

Aliases are mapped to the schema’s canonical kind.

pub fn register_migrator( &mut self, kind: NodeKindKey, migrator: Arc<dyn NodeKindMigrator>, ) -> &mut Self

Registers a per-kind data migrator.

The migrator is stored as an in-memory hook (not serialized as part of the schema data).

pub fn resolve_kind<'a>(&'a self, kind: &'a NodeKindKey) -> &'a NodeKindKey

Resolves an input kind to a canonical kind (via aliases).

pub fn get(&self, kind: &NodeKindKey) -> Option<&NodeSchema>

Looks up a schema by canonical kind key.

pub fn schemas(&self) -> impl Iterator<Item = &NodeSchema>

Iterates all registered schemas in deterministic order (by kind key).

pub fn view_descriptor( &self, kind: &NodeKindKey, ) -> Option<NodeKindViewDescriptor>

Returns the adapter-facing descriptor for a node kind or alias.

pub fn view_descriptors(&self) -> Vec<NodeKindViewDescriptor>

Returns adapter-facing node-kind descriptors in deterministic order.

pub fn instantiate_node( &self, kind: &NodeKindKey, pos: CanvasPoint, ) -> Result<NodeInstantiation, NodeInstantiationError>

Instantiates a node kind or alias with freshly allocated node and port ids.

pub fn instantiate_node_with_ids( &self, kind: &NodeKindKey, node_id: NodeId, pos: CanvasPoint, port_ids: impl IntoIterator<Item = PortId>, ) -> Result<NodeInstantiation, NodeInstantiationError>

Instantiates a node kind or alias with caller-provided ids.

Trait Implementations

impl Clone for NodeRegistry

fn clone(&self) -> NodeRegistry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NodeRegistry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for NodeRegistry

fn default() -> NodeRegistry

Returns the “default value” for a type.
