Struct GraphBuilderV2 

pub struct GraphBuilderV2<'a> { /* private fields */ }

Builder for constructing CodeGraphV2.

Provides a convenient API for adding symbols and relationships to the graph.

Example

let mut registry = SymbolRegistry::new();
let mut builder = GraphBuilderV2::new(&mut registry);

let foo = builder.add_symbol(SymbolPath::parse("mylib::foo")?, SymbolKind::Function)?;
let bar = builder.add_symbol(SymbolPath::parse("mylib::bar")?, SymbolKind::Function)?;
builder.add_call(foo, bar);

let graph = builder.build();

Implementations

impl<'a> GraphBuilderV2<'a>

pub fn new(registry: &'a mut SymbolRegistry) -> Self

Create a new builder.

pub fn with_capacity( registry: &'a mut SymbolRegistry, nodes: usize, edges: usize, ) -> Self

Create a new builder with pre-allocated capacity.

pub fn add_symbol( &mut self, path: SymbolPath, kind: SymbolKind, ) -> Result<SymbolId, RegistrationError>

Add a symbol to both registry and graph.

Returns the SymbolId for the added symbol. Also adds the symbol to the kind index for efficient kind-based queries.

pub fn add_existing_symbol(&mut self, id: SymbolId, kind: SymbolKind)

Add an existing symbol to the graph (already registered in registry).

Use this when the symbol is already registered but not yet in the graph.

pub fn add_crate_root( &mut self, path: SymbolPath, ) -> Result<SymbolId, RegistrationError>

Add a crate root.

pub fn add_existing_crate_root(&mut self, id: SymbolId)

Add an existing symbol as a crate root.

pub fn add_contains(&mut self, parent: SymbolId, child: SymbolId)

Add a Contains relationship (parent → child).

pub fn add_call(&mut self, caller: SymbolId, callee: SymbolId)

Add a Calls relationship (caller → callee).

pub fn add_implements(&mut self, implementor: SymbolId, trait_or_type: SymbolId)

Add an Implements relationship (implementor → trait/type).

pub fn add_match_expr( &mut self, function_id: SymbolId, file_id: FileId, enum_id: SymbolId, offset: u32, line: u32, )

Add a match expression to a function (String-free version).

Uses FileId and SymbolId instead of PathBuf and String.

Arguments

• function_id - The function containing the match expression
• file_id - The file containing the match expression
• enum_id - The enum being matched
• offset - Byte offset in the file
• line - Line number (1-indexed)

pub fn build(self) -> CodeGraphV2

Build the graph, consuming the builder.

Note: Unlike V1, indices are built incrementally during add_symbol, so no post-build index rebuild is needed.

pub fn registry(&self) -> &SymbolRegistry

Get a reference to the registry.

pub fn registry_mut(&mut self) -> &mut SymbolRegistry

Get a mutable reference to the registry.

pub fn graph(&self) -> &CodeGraphV2

Get a reference to the graph being built.
