[txtai](https://github.com/neuml/txtai) executes machine-learning workflows to transform data and build AI-powered text indices to perform similarity search.

This repository contains Rust bindings for the txtai API. Full txtai functionality is supported.

## Installation

Add the following lines to your project `Cargo.toml` file:

```toml
[dependencies]
txtai = { version = "3.1" }
tokio = { version = "0.2", features = ["full"] }
```

This adds txtai as a dependency as well as tokio given txtai uses async io.

## Examples
The examples directory has a series of examples that give an overview of txtai. See the list of examples below.

txtai.rs connects to a txtai api instance. See [this link](https://github.com/neuml/txtai#api) for details on how to start a new api instance.

Once an api instance is running, do the following to run the examples.

```
git clone https://github.com/neuml/txtai.rs
cd txtai.rs/examples/demo
cargo run
```
