Struct PartitionConfig 

pub struct PartitionConfig {
    pub chunk_size: usize,
    pub max_memory_bytes: Option<usize>,
    pub accumulation: AccumulationStrategy,
    pub parallel: bool,
    pub epsilon: f64,
}

Configuration for a partitioned reduction.

Fields

chunk_size: usize

Number of elements per partition chunk.

max_memory_bytes: Option<usize>

Optional memory budget in bytes.

accumulation: AccumulationStrategy

How to accumulate across chunks.

parallel: bool

Whether to run chunks in parallel (placeholder flag; actual parallelism requires a rayon dependency that is not present in this crate).

epsilon: f64

Numerical stability epsilon (used in log-sum-exp and division guards).

Implementations

impl PartitionConfig

pub fn new(chunk_size: usize) -> Self

Create a new config with the given chunk size and default settings.

pub fn memory_bounded(max_bytes: usize, element_size: usize) -> Self

Derive chunk size from a memory budget and the element size in bytes.

The computed chunk size is max_bytes / element_size, clamped to at least 1.

pub fn with_strategy(self, strategy: AccumulationStrategy) -> Self

Set the accumulation strategy.

pub fn with_parallel(self, parallel: bool) -> Self

Enable or disable parallel chunk processing.

pub fn chunks_for_size(&self, total_elements: usize) -> usize

Return the number of chunks needed to process total_elements elements.

Trait Implementations

impl Clone for PartitionConfig

fn clone(&self) -> PartitionConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PartitionConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PartitionConfig

fn default() -> Self

Returns the “default value” for a type.
