Crate stt_build 

Library facade for the stt-build crate.

The CLI binary lives at src/main.rs; this lib target exposes the same modules so integration tests under tests/ and external probes can drive the pipeline programmatically.

Re-exports

pub use tiler::encode_single_tile;

Modules

build_options

Shared flag → config parsing (--temporal-bucket, --vector-group, --quantize-*, per-tile budgets, attribute filters) used by both the stt-build CLI and the stt-serve dynamic server, so a live-served tile is configured byte-identically to one built offline. Shared flag → config parsing used by BOTH the stt-build CLI and the stt-serve dynamic server.

clip

Trajectory clipping for spatiotemporal tile distribution

columnar

Build Arrow ColumnarLayers from parsed features and clipped segments.

input

GeoParquet input parsing and feature loading

quadbin

CARTO Quadbin cell encoding — the build-side inverse of the TS decoder in packages/deck.gl/src/quadbin-cell.ts.

simplify

Line simplification for lower zoom levels

style_hints

Build-time style_hints collection (--style-hints): bounded per-property value sampling + layer-kind counting over the loaded features, feeding the generic profiler in stt_optimize::analysis::properties. Build-time style_hints collection (stt-build --style-hints).

summary

Build the server-aggregated summary tier alongside the raw tier.

tiler

Tile generation: clip trajectories, bucket features spatially and temporally, and emit Arrow ColumnarLayers per tile.
