Struct Lzma2Options 

pub struct Lzma2Options { /* private fields */ }

Available on crate feature compress only.

Options for LZMA2 compression.

Implementations

impl Lzma2Options

pub fn from_level(level: u32) -> Self

Creates LZMA2 options with the specified compression level. Encoded using a single thread.

Arguments

• level - Compression level (0-9, clamped to this range)

pub fn from_level_mt(level: u32, threads: u32, chunk_size: u64) -> Self

Creates LZMA2 options with the specified compression level. Encoded using a multi-threading.

Arguments

• level - Compression level (0-9, clamped to this range)
• threads - Count of threads used to compress the data
• chunk_size - Size of each independent chunk of uncompressed data. The more streams can be created, the more effective is the multi threading, but the worse the compression ratio will be (value will be clamped to have at least the size of the dictionary).

pub fn set_dictionary_size(&mut self, dict_size: u32)

Sets the dictionary size used when encoding.

Will be clamped between 4096..=4294967280.
