Dear Boost,

I'd like to draw attention to my double_ended library, founded by GSoC 2015. It provides two containers, briefly described below. Given there's interest, I'd like to propose this library later.

Documentation: http://erenon.hu/double_ended/ Source: https://github.com/erenon/double_ended

Short overview:

`devector` is a hybrid of the standard vector and deque containers, as well as the `small_vector` of Boost.Container. It offers cheap (amortized constant time) insertion at both the front and back ends, while also providing the regular features of `std::vector`, in particular the contiguous underlying memory. In contrast to the standard vector, however, `devector` offers greater control over its internals. Like `small_vector`, it can store elements internally without dynamically allocating memory.

`batch_deque` is very similar to the standard `deque`, with a slight twist. It lets you specify its segment size: The size of the contiguous memory segments it uses to store its elements. This provides a consistent layout across platforms, and lets you iterate over the segments with batch operations.

Functions look useful, and thoughtfully designed. Documentation is excellent - only adding an (auto-)index would perfect it. This would at least give a quick index of functions: the synopsis from Doxygen is a bit unintuitive to see how to use at first (and I've made the function link names appear in bold to help to better see the wood from the trees using a custom Cascading style sheet). Contact me off-list if you would like any help to produce an index (not as painful as the rest of the toolchain ;-) Paul --- Paul A. Bristow Prizet Farmhouse Kendal UK LA8 8AB +44 (0) 1539 561830
