runtimed

lilrunt

The runtimed project provides Rust libraries for working with Jupyter.

Libraries

  • jupyter-protocol: Core types for Jupyter messages, independent of the underlying transport
  • jupyter-websocket-client: Connect to Jupyter servers, both local and remote, over WebSockets
  • nbformat: Parse and work with Jupyter Notebooks
  • runtimelib: Interact natively with Jupyter kernels over ZeroMQ

Reference Implementation

CLI & Desktop Tools

For the runt CLI and desktop applications (sidecar, notebook), see runtimed/runt.

Goal

The goal of runtimed is to provide Rust developers with simple, easy to use, and powerful access to interactive computing. We want to enable a new generation of builders to:

  • Create new notebook applications
  • Create new kinds of REPLs
  • Allow large language models to reason about code and data
