Working with bitstreams. The best type to represent bits
Also there's a library that is basically a resizable bitset with extra features. Here's the link: https://github.com/ClaasBontus/bitset2
- bitset2 now supports 128 bit integers

(Don't) crank up the warnings to 11
The PR in question seems to be https://github.com/RoaringBitmap/CRoaring/pull/446
I agree that the GitHub analyses are worse than useless, but I also think it highlights the friction between intrinsics and the program in which they appear. There probably is a better model.

Progress in building an 100% rust lang program.
Installation completed the program build successfully!! https://www.reddit.com/r/openbsd/comments/yux513/comment/iwbm72c/?context=3 I configured 2 different files in .cargo (thanx @ivan_linux for https://github.com/RoaringBitmap/CRoaring/pull/412) and .profile ( https://rust-lang.github.io/rust-bindgen/requirements.html#openbsd ) But when I try to start the program unfortunately the node not starting and I get the following errors.
- I will need your help to complete (if possible) a rust lang program installation

How do Games manage NPC schedules?
I use a fake database paired with compressed bits for flags and integer compression for various other traits. They follow a navigation guide similar to wind for foliage.

Help with CFFI, C struct decoding, best practices / portability
I've been using CFFI to access the CRoaring C API to Roaring Bitmaps. It's been pretty easy so far. However I'm not experienced in lisp FFI, and I'm unsure of the way to go about the task of decoding a C structure used for iteration in the C CPI. The structure is as follows: ``` typedef struct roaring_uint32_iterator_s { const roaring_bitmap_t *parent; // owner int32_t container_index; // point to the current container index int32_t in_container_index; // for bitset and array container, this is out // index int32_t run_index; // for run container, this points at the run

FFI advice sought
I have a build shared library build of the C API for Roaring Bitmaps and I'm just trying to figure out the right path forward to write a lisp interface to it on sbcl.

C Deep
CRoaring - C implementation of Roaring bitmaps. Apache-2.0
What are some alternatives?
When comparing bitset2 and CRoaring you can also consider the following projects:
bit_set - Rebooting the std::bitset franchise
TurboPFor - Fastest Integer Compression
itsy_bitsy - Bit containers, sequences, and views for everyone. 🕷️
C-album - An album of C code to study and investigate.
better_bitset - A better `std::bitset` that supports scanning for bits optimally
