Struct CompactStats 

pub struct CompactStats {
    pub tiles_read: usize,
    pub tiles_written: usize,
    pub tiles_deduplicated: usize,
    pub bytes_before: usize,
    pub bytes_after: usize,
    pub reduction_pct: f64,
}

Quantitative summary of a single compaction run.

Fields

tiles_read: usize

Number of logical tiles read from the source archive (after run-length expansion). Equals PmTilesReader::enumerate_tiles length.

tiles_written: usize

Number of tiles dispatched to the builder. When deduplication is enabled, tiles whose content was already seen are still dispatched (the builder deduplicates the physical payload) but are counted under tiles_deduplicated.

tiles_deduplicated: usize

Number of tiles whose byte content was identical to a previously-seen tile. Only meaningful when CompactOptions::deduplicate is true; otherwise always 0.

bytes_before: usize

Total byte length of the source archive.

bytes_after: usize

Total byte length of the compacted output archive.

reduction_pct: f64

Percentage reduction in archive size: (bytes_before - bytes_after) / bytes_before * 100.0. Returns 0.0 when bytes_before == 0.
