Struct PartitionedDecoder 

pub struct PartitionedDecoder { /* private fields */ }

Partitioned decoder that tiles the syndrome lattice into independent regions for parallel decoding.

Each tile of size tile_size x tile_size is decoded independently using the inner decoder, then corrections at tile boundaries are merged to form a globally consistent correction set.

This architecture enables:

• Sublinear wall-clock scaling with tile parallelism
• Bounded per-tile working set for cache efficiency
• Graceful degradation: tile boundary errors add O(1/tile_size) overhead to the logical error rate

Implementations

impl PartitionedDecoder

pub fn new(tile_size: u32, inner_decoder: Box<dyn SurfaceCodeDecoder>) -> Self

Create a new partitioned decoder.

tile_size controls the side length of each tile (e.g., 8 for 8x8 regions). The inner_decoder is used to decode each tile.

Trait Implementations

impl SurfaceCodeDecoder for PartitionedDecoder

fn decode(&self, syndrome: &SyndromeData) -> Correction

Decode a syndrome and return the inferred correction.

fn name(&self) -> &str

Human-readable name for this decoder.
