A pure-rust implementation of [zlib](https://www.zlib.net/manual.html).
This is a low-level implementation crate for use in libraries like `flate2` and `rustls`. For a more high-level interface, use [`flate2`](https://crates.io/crates/flate2).
For a [zlib](https://www.zlib.net/manual.html) -compatible rust api of this crate, see [`libz-rs-sys`](https://crates.io/crates/libz-rs-sys). For instructions on integrating zlib-rs into a C library, see [`libz-rs-sys-cdylib`](https://crates.io/crates/libz-rs-sys-cdylib).
## Example
```rust
use zlib_rs::ReturnCode;
use zlib_rs::{DeflateConfig, compress_bound, compress_slice};
use zlib_rs::{InflateConfig, decompress_slice};
let input = b"Hello World";
// --- compress ---
let mut compressed_buf = vec![0u8; compress_bound(input.len())];
let (compressed, rc) =
compress_slice(&mut compressed_buf, input, DeflateConfig::default());
assert_eq!(rc, ReturnCode::Ok);
// --- decompress ---
let mut decompressed_buf = vec![0u8; input.len()];
let (decompressed, rc) =
decompress_slice(&mut decompressed_buf, compressed, InflateConfig::default());
assert_eq!(rc, ReturnCode::Ok);
assert_eq!(decompressed, input);
```
