The wfc-rs crate is a wrapper for the krychu/wfc implementation of Wave Function Collapse.
The wfc library is manually wrapped with extern functions, and a small, more ideomatic Rust wrapper is provided.
Note that this is an early, but working version.
Once the crate has been added to Cargo.toml as:
wfc_rs = "0.5"
create a WfcImage with from_vec or from_file:
let image = WfcImage::from_file("data/cave.png")?;
This creates an optional NonNull, which contains a pointer to the underlying WfcImage structure. This structure is a repr(C) struct that matches the 'wfc.h' structure 'wfc_image'.
and then a Wfc structure from this image, as well as the configuration settings:
let mut wfc = Wfc::overlapping(32, 32, image, 3, 3, true, true, true, true)?;
With this Wfc, you can run an interation with 'run'
and either export an input:
or get the raw pixel data as a Vec:
let bytes = wfc.vec();
