[dependencies]
# When this feature is disabled, zlib will be built in Z_SOLO mode which
# removes dependency on any external libraries like libc at the cost of
# eliminating some high-level functions like gz*, compress* and
# uncompress, and requiring embedder to provide memory allocation
# routines to deflate and inflate.

[features]
default = ["libc", "stock-zlib"]
# By default, libz-sys uses stock zlib. 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.
