Enum ChunkedArchiveOptions 

pub enum ChunkedArchiveOptions {
    V2 {
        minimum_chunk_size: usize,
        chunk_alignment: usize,
        compression_level: i32,
    },
    V3 {
        compression_algorithm: CompressionAlgorithm,
    },
}

Options for constructing a chunked archive.

Variants

V2

A chunked-compression V2 archive will be created.

Fields

minimum_chunk_size: usize

Chunked-compression V2 has a limit of 1023 chunks. If splitting the data up into minimum_chunk_sized chunks would exceed this limit then the chunk size increased by chunk_alignment until fewer than 1024 are required. minimum_chunk_size must be a multiple of chunk_alignment.

chunk_alignment: usize

The chosen uncompressed chunk size must always be a multiple of this value.

compression_level: i32

The Zstd compression level to use when compressing chunks.

V3

A chunked-compression V3 archive will be created.

Fields

compression_algorithm: CompressionAlgorithm

The compression algorithm to use to compress the chunks.

Implementations

impl ChunkedArchiveOptions

pub fn compressor(&self) -> Compressor

Constructs a compressor to compress chunks based on the specified options.

pub fn thread_local_compressor(&self) -> ThreadLocalCompressor

Constructs a compressor object that uses a thread local compressor to compress chunks based on the specified options.

Trait Implementations

impl Clone for ChunkedArchiveOptions

fn clone(&self) -> ChunkedArchiveOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChunkedArchiveOptions

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

Formats the value using the given formatter.

impl PartialEq for ChunkedArchiveOptions

fn eq(&self, other: &ChunkedArchiveOptions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
