From 0fdcd034ca34b0808824e05336725c817e3e29e9 Mon Sep 17 00:00:00 2001 From: Chris Lyons Date: Sat, 7 Mar 2026 16:37:40 -0500 Subject: [PATCH 1/4] feat: add cloud-native checker domain with 6 rules Cloud checker rules (src/checkers/cloud/): - format_recommendation: flag non-cloud-optimized formats (Shapefile, large GeoJSON, GeoPackage) - crs_metadata: validate CRS metadata is embedded in dataset - multi_file_integrity: check Shapefile sidecar files (.shx, .dbf, .prj, .cpg) - spatial_index: stub for FlatGeobuf/GeoParquet spatial index verification - compression: flag large uncompressed files, stub for GeoParquet codec check - file_size: flag >2GB files, Shapefile limit, tiny GeoParquet overhead Core changes: - Add Cloud variant to Domain enum (rule.rs) - Register cloud module in checkers/mod.rs - Add cloud/cloud-native to parse_domain in main.rs - Fix Rust 2024 compilation warnings (topology_gaps, topology_overlaps, distance_distortion, datum_mismatch, summary) Update README with implemented feature inventory (20 rules across 3 domains). 154 tests passing, clippy clean. --- README.md | 34 +++- src/checkers/cloud/compression.rs | 118 ++++++++++++++ src/checkers/cloud/crs_metadata.rs | 150 ++++++++++++++++++ src/checkers/cloud/file_size.rs | 146 +++++++++++++++++ src/checkers/cloud/format_recommendation.rs | 139 ++++++++++++++++ src/checkers/cloud/mod.rs | 19 +++ src/checkers/cloud/multi_file_integrity.rs | 143 +++++++++++++++++ src/checkers/cloud/spatial_index.rs | 89 +++++++++++ src/checkers/data_quality/topology_gaps.rs | 2 +- .../data_quality/topology_overlaps.rs | 2 +- src/checkers/mod.rs | 1 + src/checkers/projection/datum_mismatch.rs | 6 +- .../projection/distance_distortion.rs | 2 +- src/core/rule.rs | 3 + src/main.rs | 1 + src/profile/summary.rs | 2 +- 16 files changed, 848 insertions(+), 9 deletions(-) create mode 100644 src/checkers/cloud/compression.rs create mode 100644 src/checkers/cloud/crs_metadata.rs create mode 100644 src/checkers/cloud/file_size.rs create mode 100644 src/checkers/cloud/format_recommendation.rs create mode 100644 src/checkers/cloud/mod.rs create mode 100644 src/checkers/cloud/multi_file_integrity.rs create mode 100644 src/checkers/cloud/spatial_index.rs diff --git a/README.md b/README.md index 9de4afa..883baa6 100644 --- a/README.md +++ b/README.md @@ -4,7 +4,7 @@
