Struct GraphQueryAdapter 

pub struct GraphQueryAdapter<'a> { /* private fields */ }

Query adapter for the unified graph.

Wraps a CodeGraph and exposes query-focused helpers.

Implementations

impl<'a> GraphQueryAdapter<'a>

pub fn new(graph: &'a CodeGraph) -> Self

Creates a new adapter for the given graph.

pub fn get_parent_scope(&self, node_id: NodeId) -> Option<NodeId>

Get the parent scope (container) of a node.

Finds the container by looking for an incoming Contains edge. For example, a method’s parent scope is its containing class.

Returns

Some(parent_node_id) if the node has a parent container, None otherwise.

pub fn get_ancestor_scopes(&self, node_id: NodeId) -> Vec<NodeId>

Get all ancestor scopes of a node (parent chain up to root).

Returns the chain of containing scopes from immediate parent to top-level. For example, for a method in a nested class: [immediate_class, outer_class, module]

Returns

Vector of ancestor node IDs, from immediate parent to root.

pub fn get_scope_info(&self, node_id: NodeId) -> Option<ScopeInfo>

Get scope information for a node.

Returns the scope type (derived from NodeKind) and name.

Returns

Some(ScopeInfo) if the node exists, None otherwise.

pub fn get_containing_scope_info(&self, node_id: NodeId) -> Option<ScopeInfo>

Get the containing scope info for a node (its parent’s scope info).

This is a convenience method that combines get_parent_scope and get_scope_info.

Returns

Some(ScopeInfo) of the parent container, None if no parent exists.

pub fn get_references_to(&self, node_id: NodeId) -> Vec<ReferenceInfo>

Get all references to a node.

Finds incoming References, Calls, Imports, and FfiCall edges.

Returns

Vector of ReferenceInfo for all references to this node.

pub fn node_has_references(&self, node_id: NodeId) -> bool

Check if a node has any references (is referenced by other symbols).

This is more efficient than get_references_to when you only need to check existence, not enumerate all references.

Returns

true if the node has at least one incoming reference edge.

pub fn find_references_to_symbol(&self, symbol_name: &str) -> Vec<ReferenceInfo>

Find nodes by name and return their references.

This is useful for implementing references:symbol_name predicate.

Arguments

• symbol_name - The name to search for (exact match or suffix match with ::)

Returns

Vector of ReferenceInfo for all references to matching symbols.

pub fn graph(&self) -> &CodeGraph

Returns a reference to the underlying graph.
