If you set default-features=false, 44# enable the zlib-ng feature, and don't enable the stock-zlib feature, libz-sys 45# will instead supply the high-performance zlib-ng, in zlib-compat mode. Any 46# application or library designed for zlib should work with zlib-ng in 47# zlib-compat mode, as long as it doesn't make assumptions about the exact size 48# or output of the deflated data (e.g. "compressing this data produces exactly 49# this many bytes"), and as long as you don't also dynamically pull in a copy 50# of stock zlib (which will produce conflicting symbols). If a single crate in 51# the dependency graph requests stock-zlib (or doesn't disable default 52# features), you'll get stock zlib. 53# 54# Library crates should use: 55# libz-sys = { version = "1.1.0", default-features = false, features = ["libc"] } 56# (Omit the libc feature if you don't require the corresponding functions.) 57# 58# This allows higher-level crates depending on your library to opt into zlib-ng 59# if desired. 60# 61# Building zlib-ng requires cmake. 62zlib-ng = ["libc", "cmake"] 63stock-zlib = [] 64# Deprecated: the assembly routines are outdated, and either reduce performance 65# or cause segfaults. 66asm = [] 67# Enable this feature if you want to have a statically linked libz 68static = [] 69
