Struct ModuleNode 

pub struct ModuleNode<'tree> { /* private fields */ }

Immutable object-oriented interface to a ModuleTree

Implementations

impl ModuleNode<'_>

pub fn index(self) -> usize

Gets the index from this node

pub fn parent(self) -> Option<Self>

Gets this node’s parent

pub fn selfty(self) -> Option<Self>

Gets the node’s “encompassing Type”

pub fn child(self, name: &Sym) -> Option<Self>

Gets the child of this node with the given name

pub fn item(self, name: &Sym) -> Option<usize>

Gets a stack value in this node with the given name

pub fn is_ty(self) -> Option<bool>

Returns true when this node represents type information

pub fn children(&self) -> Option<&HashMap<Sym, usize>>

Returns a reference to this node’s children, if present

pub fn items(&self) -> Option<&StackBinds>

Returns a reference to this node’s items, if present

pub fn find(self, path: &[PathPart]) -> (Self, &[PathPart])

Traverses a path starting at this node

Returns a new node, and the unconsumed path portion.

pub fn find_item(&self, path: &[PathPart]) -> Option<usize>

Traverses a path starting at this node

Returns an item address if the path terminated in an item.
