Crate manifold_csg 

Safe Rust bindings to manifold3d — a geometry kernel for constructive solid geometry (CSG).

This crate provides safe, ergonomic wrappers around the manifold3d C API. For details on the underlying algorithms and behavior, see the upstream documentation.

• Manifold — 3D solid with boolean operations (union, difference, intersection)
• CrossSection — 2D region with offset, boolean, and hull operations
• MeshGL64 / MeshGL — mesh data transfer (f64 and f32 precision)
• triangulate_polygons — constrained Delaunay triangulation of 2D polygons

Key features

• f64 precision: Uses MeshGL64 to avoid f32 precision loss
• Send + Sync safe: All types can be moved across threads and shared for concurrent reads
• Memory safe: All C handles are freed automatically via Drop
