Fields

chunk: ChunkParams

block_size: u32

0 = granular (one chunk per blob, best random access); otherwise consecutive unique chunks are compressed together in blocks of up to this many bytes (default 1 MiB).

level: i32

codec: CodecChoice

Codec(s) the packer may use per block.

effort: u8

Codec-choice effort for CodecChoice::Best, 1..=5 (codec::CodecOptions::effort): 1 = zstd only, 2 = zstd or xz decided on a sample of each block, 3 = zstd, xz or PPMd decided on a sample, 4 = 3 plus an xz check when PPMd wins, 5 = every codec on every block (default). Blocks of at most 128 KiB always run the full trial. Not recorded in the archive.

train_dict: bool

Train a zstd dictionary on the first dict_warmup bytes of unique chunks (granular mode only).

dict_size: usize

dict_warmup: usize

container_aware: bool

password: Option<String>

kdf: KdfParams

sign_seed: Option<[u8; 32]>

keep_mtime: bool

timestamp: bool

profile: String

limits: Limits

batch: usize

Blocks compressed in parallel per batch (0 = number of CPU threads).

references: Vec<PathBuf>

Reference archives: chunks already present in them are referenced, not stored.

recipients: Vec<Recipient>

Hybrid X25519 + ML-KEM-768 recipients (public key bytes); each gets its own stanza.

canonical: bool

Also store canonical views (DOCX -> Markdown, PDF -> text) as derived entries under .tsaur/views/ (hybrid fidelity: originals stay bit-exact, views are pre-computed).

delta: bool

Delta coding: blocks of an entry that looks like a new version of an earlier entry (same path in a reference archive, or a similarly named earlier entry of this archive) are also tried with zstd against that earlier content as dictionary; the smaller encoding wins.

jpeg_recompression: bool

Recompress JPEG files and PDF DCTDecode images with Lepton when the build has it. false (pack --no-lepton) stores them as they are, so that every build, including one without the lepton feature, can read the archive.

Trait Implementations

impl Clone for PackOptions

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PackOptions

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

Formats the value using the given formatter.

impl Default for PackOptions

fn default() -> Self

Returns the “default value” for a type.
