Struct CompactOptions 

pub struct CompactOptions {
    pub deduplicate: bool,
    pub sort_by_tile_id: bool,
    pub preserve_metadata: bool,
}

Options controlling how compact_archive and compact_archive_with_stats operate.

Fields

deduplicate: bool

When true, tiles with identical byte content share a single physical payload in the output archive. The builder already deduplicates by FNV-1a hash; this flag additionally tracks duplicate dispatches so that CompactStats::tiles_deduplicated is accurate.

When false, every tile is dispatched to the builder individually, but the builder still deduplicates by content hash unless disabled.

Default: true.

sort_by_tile_id: bool

When true, tiles are fed to the builder in ascending tile-ID order (Hilbert-curve order), matching the PMTiles v3 clustered layout recommendation. PmTilesReader::enumerate_tiles already returns tiles sorted by tile ID, so enabling this flag is a no-op in practice; it exists to document intent and allow future optimisations.

Default: true.

preserve_metadata: bool

When true, the following header fields from the source archive are propagated to the output archive:

• tile type
• zoom range (min_zoom, max_zoom)
• geographic bounding box (min/max lon/lat)
• centre longitude, latitude, and zoom

When false, the builder uses its own defaults (tile type Unknown, zoom range 0–0, world bounding box).

Default: true.
