ex_ratatui – Elixir bindings for ratatui via Rustler NIFs

Nice to knowtooling

What changed: The crate provides Elixir bindings for the ratatui library using Rustler NIFs.
Production impact: The source does not say.
Try it: Add ex_ratatui to an Elixir project and call a Rust function.

Understand it, then run it

The crate ex_ratatui adds Elixir bindings for the Rust TUI library ratatui. Elixir can call Rust code through NIFs, and ex_ratatui uses the Rustler crate to expose ratatui functions to Elixir. This means an Elixir program can build a terminal UI using Rust’s ratatui without writing Rust code itself. The change is only in the crate; the Rust language or standard library is unchanged.

Run it now

Todayrust

// This program demonstrates that the Rust language has not changed for this crate.
// The ex_ratatui crate is an Elixir binding; it does not compile in Rust alone.
// We simply print a message to show the program runs.
fn main() {
    println!("ex_ratatui is an Elixir binding; Rust code alone does not use it.");
}

What it printed when we ran it on Rust 1.98.1 (edition 2024)

ex_ratatui is an Elixir binding; Rust code alone does not use it.

Run sends this program (for Solidity, the contract and its tests) to our own sandbox, where it is compiled and run once, with no network, and what it printed or the test report comes back here. Nothing is kept. Runs are counted per visitor for the day so everyone gets a turn; the details are on the legal page.
