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 whih 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. flate2 supports many different implementations.
