Crate bymsdfgen_core 

bymsdfgen-core

The core crate of bymsdfgen, a pure-Rust msdf generator and pure-Rust alternative to msdfgen: generation of conventional and multi-channel signed distance fields from vector shapes, with no C++ toolchain and no FFI.

Design highlights versus the C++ original:

• Zero-cost dispatch: edges are a Copy geometry::EdgeSegment enum (match) instead of a virtual class hierarchy behind heap pointers.
• Data-oriented layout: contours store segments in flat, contiguous Vecs.
• Typed coordinate spaces: math::typed newtypes make space mismatches a compile error rather than a silent logic bug.
• Fearless parallelism: row-parallel generation via rayon (feature parallel) with compile-time data-race freedom.

Modules

bitmap

Owning, channel-generic pixel buffer. Port of core/Bitmap.h + BitmapRef.hpp.

coloring

Edge coloring heuristics. Port of core/edge-coloring.cpp.

correction

MSDF error correction. Port of core/MSDFErrorCorrection.cpp and core/msdf-error-correction.cpp (modern, non-legacy path).

distance

Per-edge distance selection and per-contour combination.

generator

Distance-field generation: projection/mapping, configs, and the generators.

geometry

Data-oriented shape geometry: edge segments, contours, shapes.

math

Math foundations: vectors, scalar helpers, signed distance, ranges and the zero-cost coordinate-space newtypes.

raster

Scanline rasterization and sign correction.
