Struct RegionRef 

pub struct RegionRef {
    pub path: LevelPath,
    pub node: BloqNodeId,
}

A program-unique address of one region node: the path to its graph level plus its level-local id.

Both halves are needed because BloqNodeIds are level-local; see LevelPath.

Fields

path: LevelPath

The level the region node lives at; empty for the top level.

node: BloqNodeId

The region node’s id within that level.

Implementations

impl RegionRef

pub fn resolve<'a>(&self, bloq: &'a Bloq) -> Option<&'a RegionNode>

The region this reference names, or None once the program has been edited out from under it (a stale path, or an id whose node is gone).
