Struct PackConfig 

pub struct PackConfig {

    pub disk: Option<PathBuf>,
    pub memory: Option<PathBuf>,
    pub output: PathBuf,
    pub compression: String,
    pub encrypt: bool,
    pub password: Option<String>,
    pub train_dict: bool,
    pub block_size: u32,
    pub cdc_enabled: bool,
    pub min_chunk: u32,
    pub avg_chunk: u32,
    pub max_chunk: u32,
    pub parallel: bool,
    pub num_workers: usize,
    pub show_progress: bool,
}

Configuration parameters for snapshot packing.

This struct encapsulates all settings for the packing process. It’s designed to be easily constructed from CLI arguments or programmatic APIs.

Examples

use hexz_core::ops::pack::PackConfig;
use std::path::PathBuf;

// Basic configuration with defaults
let config = PackConfig {
    disk: Some(PathBuf::from("disk.img")),
    output: PathBuf::from("snapshot.hxz"),
    ..Default::default()
};

// Advanced configuration with CDC and encryption
let advanced = PackConfig {
    disk: Some(PathBuf::from("disk.img")),
    output: PathBuf::from("snapshot.hxz"),
    compression: "zstd".to_string(),
    encrypt: true,
    password: Some("secret".to_string()),
    cdc_enabled: true,
    min_chunk: 16384,
    avg_chunk: 65536,
    max_chunk: 131072,
    ..Default::default()
};

Fields

disk: Option<PathBuf>

Path to the disk image (optional).

memory: Option<PathBuf>

Path to the memory image (optional).

output: PathBuf

Output snapshot file path.

compression: String

Compression algorithm (“lz4” or “zstd”).

encrypt: bool

Enable encryption.

password: Option<String>

Encryption password (required if encrypt=true).

train_dict: bool

Train a compression dictionary (zstd only).

block_size: u32

Block size in bytes.

cdc_enabled: bool

Enable content-defined chunking (CDC).

min_chunk: u32

Minimum chunk size for CDC.

avg_chunk: u32

Average chunk size for CDC.

max_chunk: u32

Maximum chunk size for CDC.

parallel: bool

Enable parallel compression (use multiple CPU cores).

num_workers: usize

Number of worker threads (0 = auto-detect).

show_progress: bool

Show progress bar (if no callback provided).
