Struct LevelPath 

pub struct LevelPath { /* private fields */ }

Path from the top level to one graph level: the chain of enclosing region body hops. Empty = the top level.

Implementations

impl LevelPath

pub fn top_level_ancestor(&self, local: BloqNodeId) -> BloqNodeId

The top-level ancestor of a node at this level: the outermost enclosing region for a nested level, else local itself.

Because ids are level-local, a node’s own local id is only a valid key for Bloq::top/SubGraph::node when the node is at the top level. For a node inside a region body, this returns the id of the outermost enclosing region — the one node on the walk from the top level down to it that a top-level lookup can resolve. Passing a body-local local id straight to a top-level lookup would silently hit the wrong node (or none); route it through here first.

pub fn segments(&self) -> &[LevelSegment]

The region-body hops from the top level down, outermost first.

pub fn is_top_level(&self) -> bool

Whether this path identifies the top level.

pub fn starts_with(&self, prefix: &Self) -> bool

Whether this path is prefix or lies inside it.

pub fn child(&self, region: BloqNodeId, body: BodySelector) -> Self

This path extended by descending into region’s body.
