# Cardano Serialization Lib

This is a library, written in Rust, for serialization & deserialization of data structures used in Cardano's Haskell implementation of Alonzo along with useful utility functions.

##### NPM packages

- [NodeJS WASM package](https://www.npmjs.com/package/@emurgo/cardano-serialization-lib-nodejs)
- [Browser (chrome/firefox) WASM package](https://www.npmjs.com/package/@emurgo/cardano-serialization-lib-browser)
- [Browser (pure JS - no WASM) ASM.js package](https://www.npmjs.com/package/@emurgo/cardano-serialization-lib-asmjs)

##### NPM packages with GC support 
Note: This package uses [weak references flag from wasm-bindgen](https://rustwasm.github.io/wasm-bindgen/reference/weak-references.html).
It uses `FinalizationRegistry` under the hood to automatically call "free" for each CSL struct when it is no longer needed. However, use this feature with caution as it may have unpredictable behaviors.
