Welcome, stranger!

These are the libraries I extracted from my last game project. They might be of interest to you. Read at your own risk.

If you do find a bug, I'll happilly talk to you, but otherwise, this project is open source in the sense that you can read the code, not in the sense that I plan to engage with people on the internet about it much.

This repository does not contain the live versions of the libraries - rather I will from time to time manually sync this code with my projects.

Notable libraries:

• wfprof: An intrusive profiler with very low overhead. Does not do call attribution. Strongly influenced by the profiler Casey built at Computer, Enhance!. Video below.

• wfarena: An arena style allocator. Supports both the block based approach as well as virtual memory. Supports resetting to a previous checkpoint. Current version is somewhat influenced by the arena in RADDebugger.

• wfgui: An immediate-style GUI. Currently not very high quality. Definitely needs more work. Video below.

• wfslab: A slab array (sometimes called a slab allocator or a bucket array). An arena-friendly (does not reallocate) array-like datastructure with stable pointers (not that Rust appreciates them).

• wfhashtrie: An arena-friendly (does not reallocate) hash table.

• wfflags: A proc-macro (a piece of Rust you execute at compile time to generate code) that turns an enum declaration into a typesafe flags type.

• wfserialize: A serialization system that supports per-struct versioning. Currently only serializes to text, but a binary backend is on the roadmap.

• wfinlinevec: Just like the arrayvec library, but you can reinterpret the bytes with mem::transmute (or a safe wrapper like bytemuck) without fear of LLVM.

And others.

The profiler (and GUI, I guess).
