Struct xz2::stream::Filters
[−]
[src]
pub struct Filters { /* fields omitted */ }A custom chain of filters to configure an encoding stream.
Methods
impl Filters[src]
fn new() -> Filters
Creates a new filter chain with no filters.
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.
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.
fn x86(&mut self) -> &mut Filters
Add a filter for x86 binaries.
fn powerpc(&mut self) -> &mut Filters
Add a filter for PowerPC binaries.
fn ia64(&mut self) -> &mut Filters
Add a filter for IA-64 (itanium) binaries.
fn arm(&mut self) -> &mut Filters
Add a filter for ARM binaries.
fn arm_thumb(&mut self) -> &mut Filters
Add a filter for ARM-Thumb binaries.
fn sparc(&mut self) -> &mut Filters
Add a filter for SPARC binaries.
