Struct GraphBuilder 

pub struct GraphBuilder { /* private fields */ }

Intermediate builder state used during graph construction.

Implementations

impl GraphBuilder

pub fn new() -> Self

Create a new empty graph builder.

pub fn get_or_create_node(&mut self, canonical_path: &str) -> ModuleId

Allocate a new node with the given canonical path and return its id. If a node with this path already exists, returns its existing id.

pub fn begin_visit(&mut self, canonical_path: &str) -> bool

Mark a module as currently being visited (for cycle detection). Returns false if the module is already being visited (cycle!).

pub fn end_visit(&mut self, canonical_path: &str)

Mark a module as fully visited.

pub fn is_visited(&self, canonical_path: &str) -> bool

Check if a module has been fully visited.

pub fn is_visiting(&self, canonical_path: &str) -> bool

Check if a module is currently being visited (would form a cycle).

pub fn get_cycle_path(&self, target: &str) -> Vec<String>

Get the cycle path when a cycle is detected.

pub fn compute_topo_order(&self, root_id: ModuleId) -> Vec<ModuleId>

Compute topological order via DFS post-order. The root module is excluded from the topo order (compiled separately).

pub fn build(self, root_id: ModuleId) -> ModuleGraph

Finalize into a ModuleGraph.

Trait Implementations

impl Default for GraphBuilder

fn default() -> Self

Returns the “default value” for a type.
