GHC.Data.Graph.Inductive.PatriciaTree

Description

An efficient implementation of `Graph` using big-endian patricia tree (i.e. Data.IntMap).

This module provides the following specialised functions to gain more performance, using GHC's RULES pragma:

- `insNode`
- `insEdge`
- `gmap`
- `nmap`
- `emap`

Code is from Hackage `fgl` package version 5.7.0.3
