Module: XZ::LibLZMA

Extended by:: FFI::Library

Defined in:: lib/xz.rb

Overview

This module wraps functions and enums used by liblzma.

Constant Summary collapse

UINT64_MAX =

The maximum value of an uint64_t, as defined by liblzma. Should be the same as

(2 ** 64) - 1

LZMA_PRESET_EXTREME = Activates extreme compression. Same as xz’s “-e” commandline switch.

1 << 31

LZMA_TELL_NO_CHECK =

0x02

LZMA_TELL_UNSUPPORTED_CHECK =

0x02

LZMA_TELL_ANY_CHECK =

0x04

LZMA_CONCATENATED =

0x08

LZMA_RESERVED_ENUM = Placeholder enum used by liblzma for later additions.

enum :lzma_reserved_enum, 0
