Struct RunStats 

#[non_exhaustive]
pub struct RunStats {
    pub output_tiles: u64,
    pub materialized_nodes: u64,
    pub peak_bytes: u64,
    pub reduction: Option<Reduction>,
}

Counters describing one run, for tests and diagnostics.

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.

output_tiles: u64

Output tiles produced.

materialized_nodes: u64

Nodes materialized because of ADR-0009.

peak_bytes: u64

Peak bytes held in working sets and materialized buffers.

This is the number the constant-memory guarantee is about: it must not grow with image height for a streaming pipeline.

reduction: Option<Reduction>

The source resolution shrink-on-load lowered, if it did.

None means the source decoded at full size — either because it has one resolution, or because the pipeline was not eligible (see shrink_on_load). Reported rather than left silent so a pipeline that expected the fast path and did not get it can be diagnosed instead of merely being slow.

Filled in by whoever applied the rewrite. Scheduler::run does not apply it: the rewrite has to happen above the choice of evaluator, or the scheduler and the reference evaluator would be handed different graphs and stop agreeing — and their agreement is the oracle the whole engine is checked against (ROADMAP M2).
