Struct Geom 

pub struct Geom { /* private fields */ }

An owned geometry that can represent any OGC Simple Feature type.

This is the main type for working with geometries. It supports:

• All geometry types: Point, LineString, Polygon, and Multi/Collection variants
• Parsing from WKT, WKB, GeoJSON, HEX, and GeoBin formats
• Spatial predicates: intersects, contains, within, covers, touches, etc.
• Serialization to various output formats

Memory is managed by the TG library and freed when dropped.
