# libz-ng-sys

A library for linking zlib-ng (`libz-ng`) to Rust programs natively, rather

than in zlib-compat mode.

zlib-ng is a high-performance implementation of zlib. zlib-ng supports building

in two modes: zlib-compat mode, in which it provides the same API as zlib and

generally works as a drop-in replacement, and native mode, in which it provides

its own API. The native API is almost identical to the zlib-compat API, except

that some types use more correct sizes (rather than the sizes required for zlib

compatibility), and the functions all have a `zng_` prefix. The latter allows

zlib and zlib-ng to coexist in the same program.

This crate provides bindings to the native zlib-ng API. However, for simplicity

of porting, this crate exports the same API as libz-sys (without the `zng_`

prefixes), making it easier to write Rust software compatible with both

libz-sys and libz-ng-sys.

# High-level API

This crate provides bindings to the raw low-level C API. For a higher-level

safe API to work with DEFLATE, zlib, or gzip streams, see

[`flate2`](https://docs.rs/flate2). `flate2` supports many different

implementations.

# Development

This crate is built from [the same sources as

`libz-sys`](https://github.com/rust-lang/libz-sys). From within those sources,

`Cargo.toml` is the manifest for `libz-sys`, and `Cargo-zng.toml` is the

manifest for `libz-ng-sys`. The script `./cargo-zng` invokes Cargo on a

temporary copy of the sources with `Cargo-zng.toml` replacing `Cargo.toml`; for

instance, use `./cargo-zng publish` to publish `libz-ng-sys`.

# Minimum Supported Rust Version (MSRV) Policy

This crate uses the same MSRV policy as the

[`flate2`](https://crates.io/crates/flate2) crate: This crate supports the

current and previous stable versions of Rust. Older versions of Rust may work,

but we don't guarantee these will continue to work.
