Module PtmapSource

Maps over integers implemented as Patricia trees.

The following signature is a subset of Map.S with type key = int, with the same specifications (not repeated here) unless specified otherwise.

These are little-endian Patricia trees, so there is no efficient ordering of keys within the structure. Consequently,

  • min/max_binding, find_first/last are rather inefficient (linear)
  • iter, fold *do not* iterate in the key order
  • bindings is *not sorted* by keys
