Struct IdGenerator 

pub struct IdGenerator { /* private fields */ }

Generates scope-aware vertex IDs for AST nodes.

Implementations

impl IdGenerator

pub fn new(file_path: &str) -> Self

Create a new generator rooted at the given file path.

pub fn push_named_scope(&mut self, name: &str)

Push a named scope (function, class, method, module, etc.).

Named scopes appear in the ID as their name: file.rs::function_name::...

pub fn push_anonymous_scope(&mut self) -> u32

Push an anonymous scope (block, statement body, etc.).

Anonymous scopes appear in the ID with a positional index: file.rs::function_name::$3::...

pub fn pop_scope(&mut self)

Pop the current scope, returning to the parent.

pub fn named_id(&self, name: &str) -> String

Generate an ID for a named node at the current scope level.

Returns the full scope-qualified ID (e.g. "src/main.rs::parse_input").

pub fn anonymous_id(&mut self) -> String

Generate an ID for an anonymous (positional) node at the current scope level.

The index is auto-incremented within the current scope. Returns the full scope-qualified ID (e.g. "src/main.rs::parse_input::$3").

pub fn field_id(&self, base_id: &str, field_name: &str) -> String

Generate an ID with a field path suffix for expression sub-nodes.

Used for expression tree paths like $3::$0.left where .left is the field name within the parent expression.

pub fn current_prefix(&self) -> String

Get the current scope prefix (all scope components joined by ::).

pub fn depth(&self) -> usize

Get the current scope depth.

pub fn reset_counter(&mut self)

Reset the child counter for the current scope.

Useful when entering a new block within the same scope level.

impl Debug for IdGenerator

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

Formats the value using the given formatter.
