One issue I had with Boost.Container deque is that it only allows customizing allocation block size for a given value type and not the container itself. This prevents having multiple deques for a given value type that use different block sizes.
It would be useful to be able to specify the block size in the deque template parameters.
I don't understand your point. You can specify the block size as an option, it's not tied to a value_type, AFAIK:
https://www.boost.org/doc/libs/master/doc/html/container/configurable_contai...
Oh, I didn't know about that option. Though it would make more sense if the block size was specified in terms of container elements rather than bytes. Oh #2, I can see there is block_size, but it is not documented as an acceptable option for deque_options. Is it actually supported? I thought, the user was supposed to specialize deque_block_size for their value type. Given that there are container-specific options for this purpose, you can consider my request fulfilled, and sorry for the noise.
