Defines TG::Geometry with immutable Geom parsing and constructor wrappers, expanded geometry predicates and accessors, Rect helpers, Hex/GeoBIN writers, raw extra_json access, read-only borrowed Line/Ring/Polygon and GeometryCollection child wrappers, value Segment wrappers, Registry reload sugar, optional ActiveRecord source helpers, and an immutable geofencing-oriented Index with owned and borrowed geometry ingestion, flat/rtree strategies, deterministic ordered id results, exact rtree allocation accounting, and native-endian packed point batch queries, and FeatureSource GeoJSON FeatureCollection extraction/build paths over vendored C sources. Ractor support is not claimed.
This gem is designed to provide a modular, complete, open-source, crowd-sourced mapping of the 650+ IANA/OLSON timezones of the world into Rails' 146 'important' timezones. A search for an existing solution showed that this has been an issue since the inception of ActiveSupport::Timezone as far back as 2012. Approaches which have been suggested included such ideas as: Making your own RTree in a spatially aware database and searching on boundaries, just don't use those timezones (yeah, that makes sense), rely on your users to set their own timezone (doesn't help if you do automated onboarding), find a better sourcing API for timezones based on GeoLookup (they almost all use OLSON/IANA). Rather than doing any of those things, it made more sense to simply complete the mapping that ActiveSupport::Timezone started on and then seemingly abandoned.
