libwce: the entropy layer of a wavelet codec, on its own
Summary
This post introduces libwce, a minimal Rust implementation of a Bit-Plane Count (BPC) style entropy layer for wavelet codecs. It explains how the entropy layer works, including predictor types and data encoding, and emphasizes that libwce is stateless and buffer-driven, intended to illustrate the entropy layer rather than a full codec. The article also surveys three demos (image_compress, mode_shootout, and stream_surgery) that demonstrate end-to-end usage, predictor comparisons, and robustness testing.
