Struct ParallelConfig 

pub struct ParallelConfig {
    pub num_threads: Option<usize>,
    pub min_chunk_size: usize,
    pub max_chunks: Option<usize>,
}

Configuration for parallel computation

Fields

num_threads: Option<usize>

Number of threads to use (default: number of CPUs)

min_chunk_size: usize

Minimum chunk size in bytes (default: 5 MB) Smaller chunks = better load balancing and cache efficiency Benchmarks show 1-5 MB is optimal for most workloads

max_chunks: Option<usize>

Maximum number of chunks (default: num_threads * 4) Limits memory usage for very large files

Implementations

impl ParallelConfig

pub fn new() -> Self

Create a new config with all defaults

pub fn with_threads(self, threads: usize) -> Self

Set the number of threads to use

pub fn with_chunk_size(self, size: usize) -> Self

Set the minimum chunk size in bytes

pub fn with_max_chunks(self, max: usize) -> Self

Set the maximum number of chunks

pub fn threads(&self) -> usize

Get the effective number of threads

pub fn max_chunks(&self) -> usize

Get the effective max chunks
