Holochain-rust

What is Holochain-rust and what is it for?

Holochain-rust is the Rust codebase for Holochain: the core that runs Holochain apps, the container code that manages them, and a development kit for writing an app's own logic in Rust. Developers use it to build Holochain applications whose logic is written in Rust and compiled to WebAssembly.

Holochain-rust is the Rust implementation of Holochain. Its README describes the repository as the home of the Holochain Rust libraries, "being rewritten from Go into Rust, and extended" — a Rust rework of an earlier Go prototype of the framework.

The repository covers three overlapping parts. The core executes a Holochain app's DNA and exposes its API functions to Zomes; the container code loads and manages multiple app instances, with a container crate that builds to an executable meant to run as a background service; and hdk-rust is a library and syntax for writing Zome code in Rust, which compiles to WebAssembly.

A concrete route is printed in the README: it names the first containers — the GUI-driven holosqape and the command-line hcshell used for test running — and points anyone who wants the tools for building Holochain applications to a Developer Preview pre-release that ships binaries for macOS, Ubuntu and Windows. The repository README is the place to start reading.
