These are drop-in replacements of the respective STL +algorithms that can be a few times faster when applied on immutable +sequences. + +For further convenience they can be passed in just a container where +the standard library algorithms require being passed in two iterators. + +.. note:: + + They are a similar idea to `structure-aware iterators`_ + but implemented using higher order functions in order to support + structures of any depth. The downside is that this sometimes + causes the compiler to generate bigger executable files. + +.. _structure-aware iterators: https://www.youtube.com/watch?v=T3oA3zAMH9M + + +----- + +.. doxygengroup:: algorithm + :project: immer + :content-only: |
