NeoFS Shared Library

This repo provides a shared library with key functionalities for interacting with NeoFS. It is built with cgo and can be used on multiple platforms and architectures.

The purpose is to avoid re-implementation of complex and risky functions of NeoFS in other languages, such as Java, Kotlin, Python, Typescript, etc.

In order to use this shared library, have a look at the specification of all provided exported methods.

Build

Make sure you have docker installed.

Then, execute:

bash cross.sh

The output, i.e., .h and .so files, will be placed in the ./libs folder.
