## What it is
Evcxr is an evaluation context for Rust comprising a Jupyter kernel, a Rust REPL, and a shared library for evaluating Rust code incrementally. It lets users run Rust code interactively in notebooks or a terminal.

## Use cases
- run rust code interactively in a jupyter notebook
- try out rust snippets in a repl
- teach rust with live coding notebooks
- prototype rust code without compiling a full project
- explore rust crates interactively

## When to choose
- you want a Jupyter kernel for Rust
- you want an interactive Rust REPL for experimentation or learning

## When to avoid
- you need a full IDE experience with debugging
- you need to build production Rust applications

## Facets
- artifact type: library
- maturity: active
- function: interpreter, developer-tools, cli
- domain: developer-tools, programming-languages, education, data-science
- platform: rust, cross-platform, cli
- tags: jupyter-kernel, repl, rust-evaluation, notebook
