If you set default-features=false, # enable the zlib-ng feature, and don't enable the stock-zlib feature, libz-sys # will instead supply the high-performance zlib-ng, in zlib-compat mode. Any # application or library designed for zlib should work with zlib-ng in # zlib-compat mode, as long as it doesn't make assumptions about the exact size # or output of the deflated data (e.g. "compressing this data produces exactly # this many bytes"), and as long as you don't also dynamically pull in a copy # of stock zlib (which will produce conflicting symbols). If a single crate in # the dependency graph requests stock-zlib (or doesn't disable default # features), you'll get stock zlib. # # Library crates should use: # libz-sys = { version = "1.1.0", default-features = false, features = ["libc"] } # (Omit the libc feature if you don't require the corresponding functions.) # # This allows higher-level crates depending on your library to opt into zlib-ng # if desired. # # Building zlib-ng requires cmake. zlib-ng = ["libc", "cmake"] stock-zlib = [] # Deprecated: the assembly routines are outdated, and either reduce performance # or cause segfaults. asm = [] # Enable this feature if you want to have a statically linked libz static = []
