Crate stac_async

Asynchronous I/O for STAC, built on stac-rs

Examples

Read a single STAC item:

let item: stac::Item = stac_async::read("data/simple-item.json").await.unwrap();

Build an API client to read from a STAC API:

use futures_util::StreamExt;
let url = "https://planetary-computer.microsoft.com/api/stac/v1";
let api_client = stac_async::ApiClient::new(url).unwrap();
// Get the first sentinel2 item using an asynchronous stream
let items = api_client.items("sentinel2-l2a", None).await.unwrap();
tokio::pin!(items);
let item = items.next().await.unwrap().unwrap();

Download assets from an item:

use stac_async::Download;
let item: stac::Item = stac_async::read("data/simple-item.json").await.unwrap();
item.download("target-directory").await.unwrap();
