Struct MapReduceConfig 

pub struct MapReduceConfig {
    pub memory_budget_bytes: u64,
    pub tile_concurrency: usize,
    pub buffer_size: usize,
    pub background_rgb: [u8; 3],
    pub blank_tile_strategy: BlankTileStrategy,
}

Configuration for the MapReduce streaming engine.

Controls memory budget, per-strip tile concurrency, channel backpressure, and tile handling options. The budget determines how many strips can be in flight simultaneously during the Map phase.

Fields

memory_budget_bytes: u64

Soft memory budget in bytes (covers all in-flight strips + accumulators).

tile_concurrency: usize

Maximum worker threads for tile extraction within each strip. 0 = single-threaded tile emission (strip-level parallelism only).

buffer_size: usize

Bounded channel capacity for tile backpressure.

background_rgb: [u8; 3]

Background colour for edge tile padding.

blank_tile_strategy: BlankTileStrategy

Blank tile handling strategy.

impl Default for MapReduceConfig

fn default() -> Self

Returns the “default value” for a type.
