-Pure rust Rust replacement for the [miniz](https://github.com/richgel999/miniz) deflate/zlib encoder/decoder using no unsafe code. Builds in [no_std](https://docs.rust-embedded.org/book/intro/no-std.html) mode, though requires the use of `alloc` and `collections` crates.

 This project is organized into a C API shell and a rust crate.
 The Rust crate is found in the [miniz_oxide subdirectory](https://github.com/Frommi/miniz_oxide/tree/master/miniz_oxide).
