Crate geometry_trait 

Geometry concepts as Rust traits. One trait per doc/concept/*.qbk.

Mirrors boost/geometry/core/{access,tag,coordinate_type, coordinate_dimension,coordinate_system}.hpp and the boost/geometry/geometries/concepts/*_concept.hpp headers.

v1 surface — only the Geometry super-trait and the Point concept land here. Subsequent tasks add Box, Segment, Linestring, Ring, Polygon, and the multi / collection concepts as siblings of Point.

Modules

corner

Indices used when addressing the two corners of a Box.

Structs

BoxTag

2D or 3D axis-aligned box (mbr / aabb) identifying tag — boost/geometry/core/tags.hpp:103.

GeometryCollectionTag

OGC Geometry Collection identifying tag — boost/geometry/core/tags.hpp:122.

LinestringTag

OGC Linestring identifying tag — boost/geometry/core/tags.hpp:94.

MultiLinestringTag

OGC MultiLinestring identifying tag — boost/geometry/core/tags.hpp:116.

MultiPointTag

OGC MultiPoint identifying tag — boost/geometry/core/tags.hpp:113.

MultiPolygonTag

OGC MultiPolygon identifying tag — boost/geometry/core/tags.hpp:119.

OGC Point identifying tag — boost/geometry/core/tags.hpp:91.

PolygonTag

OGC Polygon identifying tag — boost/geometry/core/tags.hpp:97.

PolyhedralSurfaceTag

OGC Polyhedral surface identifying tag — boost/geometry/core/tags.hpp:109.

RingTag

Convenience linear ring identifying tag — boost/geometry/core/tags.hpp:100.

SegmentTag

Convenience segment (2-points) identifying tag — boost/geometry/core/tags.hpp:106.

Enums

Closure

Whether a ring repeats its first point as its last.

PointOrder

Vertex traversal direction of a ring’s boundary.

Traits

Areal

Areal category marker — counterpart of areal_tag (boost/geometry/core/tags.hpp:75).

Box

An axis-aligned bounding box.

Geometry

Every modelled geometry has a kind (its tag) and a point type it is built from.

GeometryCollection

A collection of geometries belonging to each other.

IndexedAccess

Two-axis (Index, Dimension) access for geometries built out of a pair of corner points — Box and Segment.

Linear

Linear category marker — counterpart of linear_tag (boost/geometry/core/tags.hpp:69).

Linestring

A linestring — an ordered sequence of >= 2 points.

Multi

Multi-geometry marker — counterpart of multi_tag (boost/geometry/core/tags.hpp:63).

MultiLinestring

A multi-linestring — a collection of linestrings belonging to each other (e.g. a highway with interruptions).

MultiPoint

A multi-point — a collection of points belonging to each other.

MultiPolygon

A multi-polygon — a collection of polygons belonging to each other (e.g. Hawaii).

Point

The Point concept.

PointMut

The mutating half of the Point concept.

Pointlike

Point-like category marker — counterpart of pointlike_tag (boost/geometry/core/tags.hpp:66).

Polygon

A polygon — an exterior ring plus zero or more interior rings.

Polygonal

Polygonal category marker — counterpart of polygonal_tag : areal_tag (boost/geometry/core/tags.hpp:78). The C++ inheritance is expressed as a Rust super-trait bound, so T: Polygonal automatically implies T: Areal.

PolyhedralSurface

A polyhedral surface — a contiguous collection of polygons in 3-dimensional space that share common boundary segments.

Polylinear

Polylinear category marker — counterpart of polylinear_tag : linear_tag (boost/geometry/core/tags.hpp:72). The C++ inheritance is expressed as a Rust super-trait bound, so T: Polylinear automatically implies T: Linear.

Ring

A ring — an ordered sequence of points whose first and last either coincide (Closure::Closed) or are implicitly connected (Closure::Open).

SameAs

T: SameAs<U> holds iff T and U are the same type.

Segment

A two-point segment.

Single

Single-geometry marker — counterpart of single_tag (boost/geometry/core/tags.hpp:59).

Volumetric

Volumetric category marker — counterpart of volumetric_tag (boost/geometry/core/tags.hpp:81).

Functions

box_max

Materialise the maximum corner of a box as a crate::Point value.

box_min
