Fields

view :: ViewType

What kind of visualization is currently running

type HeapEntry = (Maybe String, Closure)

An entry in a HeapMap, consisting of an identifier and a parsed GHC heap entry

type HeapMap = [(Box, HeapEntry)]

A map of heap objects.

We're using a slow, eq-based list instead of a proper map because StableNames' hash values aren't stable enough

type PrintState = State (Integer, HeapMap, HeapMap)

The second HeapMap includes BCO pointers, needed for list visualization

data VisObject

Simple representation of objects on the heap, so they can be arranged linearly

Constructors
