Crate oxigdal_noalloc 

oxigdal-noalloc

no_std, no_alloc fixed-size geometry primitives for OxiGDAL.

This crate provides zero-allocation geometry types suitable for embedded and RISC-V environments where heap allocation is unavailable or undesirable.

Types

• Point2D — 2D point with distance and midpoint operations
• Point3D — 3D point
• BBox2D — 2D axis-aligned bounding box
• LineSegment2D — 2D line segment with intersection support
• Triangle2D — 2D triangle with area, containment, and centroid
• FixedPolygon — Fixed-capacity polygon backed by an inline array
• CoordTransform — 2D affine transform (2×3 matrix)
• GeoHashFixed — Geohash encoding stored as [u8; 12]
• NoAllocError — Error enum for no-alloc operations

Re-exports

pub use geohash::GeoHashFixed;
