Struct Filters

pub struct Filters { /* private fields */ }

A custom chain of filters to configure an encoding stream.

Implementations

impl Filters

pub fn new() -> Filters

Creates a new filter chain with no filters.

pub fn lzma1(&mut self, opts: &LzmaOptions) -> &mut Filters

Add an LZMA1 filter.

LZMA1 is the very same thing as what was called just LZMA in LZMA Utils, 7-Zip, and LZMA SDK. It’s called LZMA1 here to prevent developers from accidentally using LZMA when they actually want LZMA2.

LZMA1 shouldn’t be used for new applications unless you really know what you are doing. LZMA2 is almost always a better choice.

pub fn lzma2(&mut self, opts: &LzmaOptions) -> &mut Filters

Add an LZMA2 filter.

Usually you want this instead of LZMA1. Compared to LZMA1, LZMA2 adds support for SyncFlush, uncompressed chunks (smaller expansion when trying to compress uncompressible data), possibility to change literal_context_bits/literal_position_bits/position_bits in the middle of encoding, and some other internal improvements.

pub fn x86(&mut self) -> &mut Filters

Add a filter for x86 binaries.

pub fn powerpc(&mut self) -> &mut Filters

Add a filter for PowerPC binaries.

pub fn ia64(&mut self) -> &mut Filters

Add a filter for IA-64 (itanium) binaries.

pub fn arm(&mut self) -> &mut Filters

Add a filter for ARM binaries.

pub fn arm_thumb(&mut self) -> &mut Filters

Add a filter for ARM-Thumb binaries.

pub fn sparc(&mut self) -> &mut Filters

Add a filter for SPARC binaries.
