Rust SDK

Rust SDK for Spice.ai

The Rust SDK spice-rs is the easiest way to query Spice.ai from Rust.

It uses Apache Arrow Flight to efficiently stream data to the client and Apache Arrow Records as data frames.

Requirements

• Rust 1.77.0

Installation

Add Spice SDK

cargo add spiceai

Usage

1. Create a SpiceClient by passing in your API key to ClientBuilder. Get your free API key at spice.ai.

use spiceai::ClientBuilder;

#[tokio::main]
async fn main() {
  let mut client = ClientBuilder::new()
    .api_key("API_KEY")
    .use_spiceai_cloud()
    .build()
    .await
    .unwrap();
}

2. Execute a query and get back an Apache Arrow Flight Record Batch Stream.

let flight_data_stream = client.query("SELECT * FROM eth.recent_blocks LIMIT 10;").await.expect("Error executing query");

3. Iterate through the reader to access the records.

while let Some(batch) = flight_data_stream.next().await {
    match batch {
        Ok(batch) => {
            /* process batch */
            println!("{:?}", batch)
        },
        Err(e) => {
            /* handle error */
        },
    };
}

Usage with local Spice runtime

Follow the quickstart guide to install and run spice locally.

use spiceai::ClientBuilder;

#[tokio::main]
async fn main() {
  let mut client = ClientBuilder::new()
    .build()
    .await
    .unwrap();

  let data = client.query("SELECT trip_distance, total_amount FROM taxi_trips ORDER BY trip_distance DESC LIMIT 10;").await;
}
