Summary statistics returned after a successful pyramid generation.

Captures tile counts, level counts, and peak memory so that callers can log, display progress, or assert correctness without inspecting the sink directly. Every field is populated by [generate_pyramid] / [generate_pyramid_observed].

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

tiles_produced: u64

Total number of tiles written to the sink (including placeholders).

tiles_skipped: u64

Number of tiles that were blank and replaced with placeholders (only non-zero when BlankTileStrategy::Placeholder is used).

levels_processed: u32

Number of pyramid levels that were processed (always equals the plan’s level count).

peak_memory_bytes: u64

Peak tracked memory in bytes (raster buffers only).

bytes_read: u64

Total bytes read from the source raster.

bytes_written: u64

Total bytes written to the sink (best-effort; sum of encoded payloads).

retry_count: u64

Number of retry attempts observed across all sinks.

queue_pressure_peak: u32

Peak number of tiles held in the producer/consumer queue.

duration: Duration

Wall-clock duration of the pyramid run.

stage_durations: StageDurations

Per-stage duration breakdown (see StageDurations).

skipped_due_to_failure: u64

Number of tiles that failed terminally and were skipped under FailurePolicy::RetryThenSkip.
