Struct XzOptions 

pub struct XzOptions {
    pub lzma_options: LzmaOptions,
    pub check_type: CheckType,
    pub block_size: Option<NonZeroU64>,
    pub filters: Vec<FilterConfig>,
}

Available on crate features encoder and xz only.

Configuration options for XZ compression.

Fields

lzma_options: LzmaOptions

LZMA compression options.

check_type: CheckType

Checksum type to use.

block_size: Option<NonZeroU64>

Maximum uncompressed size for each block (None = single block). Will get clamped to be at least the dict size to not waste memory.

filters: Vec<FilterConfig>

Pre-filter to use (at most 3).

Implementations

impl XzOptions

pub fn with_preset(preset: u32) -> Self

Create options with specific preset and checksum type.

pub fn set_check_sum_type(&mut self, check_type: CheckType)

Set the checksum type to use (Default is CRC64).

pub fn set_block_size(&mut self, block_size: Option<NonZeroU64>)

Set the maximum block size (None means a single block, which is the default).

pub fn prepend_pre_filter(&mut self, filter_type: FilterType, property: u32)

Prepend a filter to the chain. You can prepend at most 3 additional filter.
