Since I haven't learned the Rust language, the code is basically learned by google or your source code. Originally wanted to add a feature that specifies love download url, but...

This copy feature can fuse all code to love.exe and copy our assets(image, audio, font, ext) to outside, ``` lfs = love.filesystem if lfs.isFused then lfs.mount(lfs.getSourceBaseDirectory(), '', true) end ```

It can patch for a empty hash, also able to convert diff to hash.

Nice. vec3.angle_to has a bug for same vec3. `v3.angle_to(v3)` will return `nan` use `acos(a:dot(b) / (a:len() * b:len()))` will fix it, so, could you add a testing case for this?...

`acos(a:dot(b) / (a:len() * b:len()))` also has this bug when a:len() * b:len() is zero or lua5.4, we should check `a == b`.

0 / 0 and acos(v) v > 1 will get nan. maybe same case make v > 1 in mycode.

I found that in some cases `abs(a:dot(b))` greater than `abs(a:len() * b:len())` I think it's because of floating point issues, `a == b` or `a == -b`

I have implement the `sqlite3_exec`. Maybe you can try it https://github.com/Codezerker/lua-ljsqlite3/commit/4efb927a6514039ec657ce977154b6ea3596f2ce

I also encountered this problem ``` Fatal error: [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Windows/D3D11RHI/Private/D3D11Util.cpp] [Line: 198] Unreal Engine is exiting due to D3D device being lost.

Compared with the slow calling performance of Lua C API, GC of these tables is obviously faster
