Python library for Hyperledger Iroha 2.

You should install rust (cargo) and python.

pip install maturin
maturin build

Architecturally python library uses rust client library. It is done via wrapping classes using rust library pyo3.

The data model of iroha itself is expected to be just classes without some special methods (without sidechannels, like doing http request). Communication channel for rust python methods using rust data model is achieved using pythonize rust library. It allows to represent almost all rust structures using python objects (via serde serialization).

Python library right now is in iroha_python/iroha2. This directory has some directories:

• iroha2 -- iroha2 library itself. Contains client and key generation at root
• iroha2.crypto -- iroha crypto bindings
• iroha2.data_model -- data model with all instructions, queries and expressions
• iroha2.sys -- raw bindings to rust structures wrapped around python objects

• iroha_python is rust sys library (sys in terms of raw bindings without abstractions)
• iroha_python/generate is used for generating classes for rust structures

There is a need to regenerate sys sources and update client library after major rust updates in data model.

cd generate
cargo run ../iroha2/sys
