Rust / WASM geo

Default stack context: tech-stack skill. This skill covers Rust/WASM geo only.

When to apply

• Turf or JS geometry is too slow (profile first — main-thread blocking > ~100ms)
• OSM parsing, map model build, isochrones, spatial indexes, graph routing
• Thousands of features, repeated geometry ops, or polygon booleans at scale
• Adding or reviewing a wasm-pack crate, wasm.ts boundary, or Vite WASM plugins

Stay on Turf (JS) for single-feature ops on small GeoJSON and interactive editing feedback during prototyping.
