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 1.73.0

Installation

Add Spice SDK

cargo add spiceai

Usage

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

use spiceai::Client;

#[tokio::main]
async fn main() {
  let mut client = Client::new("API_KEY").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 */
        },
    };
}
