Release v0.16.0

Incr_map

• New functions

  • cutoff - applies a cutoff to the values in an incremental map
  • partition_mapi' - like partition_mapi, but the callback function has an incremental input and output
  • unordered_fold_with_extra - like unordered_fold, but depends on an arbitrary extra incremental value that can be factored into the folding computation
  • merge_both_some - like merge, but the mapping callback function is only called on keys contained in both maps

• New arguments

  • Add Instrumentation module and optional instrumentation argument to all Incr_map functions, which can be used for performance profiling
  • Add optional finalize argument to unordered_fold, which can be used to change the order in which fold operations are processed

• Bug fixes

  • Fix function subrange_by_rank to handle unbounded lower bound correctly
  • Fix typo in function name mapi_mn to map_min

Erase_key

• Small new library for type-erasing the key from an incremental map without introducing an existential type

Collate

• Remove the Map_list library

  • Switch all prior uses of Map_list to the more general Incr_map_erase_key
• Make Incr_map_collate no longer a functor

• Fold

  • Add module Fold defining a fold callback function
  • Add function collate_and_fold, like collate but allows you to perform a fold over the post-filtered, pre-range-restricted data
  • Add function collate_and_fold__sort_first, like collate__sort_first but allows you to perform a fold over the post-filtered, pre-range-restricted data
