renskin

An alternate to SkinSystem for SkinRestorer. By default, it have less overhead task since SkinSystem render the whole texture on a real 3D enviroment, and this thing only render the face and hat on a 2D canvas.

Roadmap

• It works!
• TODO: Implement a proper SQL foolproof

  With proper rustegexp!

• It function as a HTTP server
• It have proper caching

  TODO: It know when to rebake new image but

  • It must know when to flush the images (bash-scripted)
  • It must let the proxy know when to cache (Edge) (50%)

• Fixed sqlx macro shills (hack)
• Streaming PNG face compositor

  Decode rows 8..15 only, compose RGBA8 with a portable scalar reference. --features avx2 enables runtime-dispatched row loads on capable x86_64.

• Support premium skin

  [!NOTE] Not yet, might need thirdparty 😭

Because the rendering stays at 300ms (composition only, with tested conditions) and the upscaling stays at 40-70ms, it is hard to implement more stuff

Requirements

• SkinRestorer dataset

How to use

Compile it yourself

• Clone
• Config with .env
• cargo build --release

The service uses the Mojang profile/session APIs by default. An optional SkinSystem MySQL resolver is enabled with DATABASE_URL; a failed connection only emits a warning and falls back. Add --ely-by to try http://skinsystem.ely.by/skins/{username}.png before Mojang. Run rskd --help for all Clap options.

Best practice

• Cache eviction runs inside the Smol executor once per hour. Set RENSKIN_CACHE_DIR for an explicit writable cache location (the container defaults to /tmp/renskin-cache).
