Struct ParallelFastCDC 

pub struct ParallelFastCDC { /* private fields */ }

FastCDC with a parallel, boundary-identical chunk_slice.

Owns the scalar chunker as its reference implementation and small-input fallback; the parallel path is purely a throughput overlay with byte-identical output (pinned by tests here and by the writer’s pack-twice determinism suite).

Implementations

impl ParallelFastCDC

pub fn new( min_size: usize, avg_size: usize, max_size: usize, ) -> Result<Self, &'static str>

Construct with explicit size parameters and the default parallel threshold.

Errors

Same contract as FastCDC::new.

pub fn with_scalar(scalar: FastCDC, threshold: usize) -> Self

Wrap an existing scalar chunker, taking large inputs to the two-phase path once data.len() >= threshold.

pub fn scalar(&self) -> &FastCDC

The scalar reference implementation this strategy wraps.

Trait Implementations

impl Chunker for ParallelFastCDC

fn chunk_slice<'a>(&self, data: &'a [u8]) -> Vec<&'a [u8]>

Split data into content-defined chunks. The concatenation of the returned slices equals data.

fn chunk_reader(&self, reader: &mut dyn Read) -> Result<Vec<Vec<u8>>>

Split a Read stream into content-defined chunks, returning each chunk as an owned Vec<u8>. Constant memory bounded by the chunker’s max chunk size plus one read buffer.

fn avg_chunk_size(&self) -> usize

Target average chunk size.

impl Clone for ParallelFastCDC

fn clone(&self) -> ParallelFastCDC

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParallelFastCDC

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

Formats the value using the given formatter.

impl Default for ParallelFastCDC

fn default() -> Self

Returns the “default value” for a type.
