Struct HrefClient 

pub struct HrefClient { /* private fields */ }

A DuckDB client bound to a specific stac-geoparquet href.

This wraps a Client with a specific href, implementing the ArrowSearchClient trait. Because duckdb::Connection is not Sync, use Mutex<HrefClient> for the async client traits (SearchClient and CollectionSearchClient).

Examples

use stac::api::ArrowSearchClient;
use stac_duckdb::HrefClient;

let client = HrefClient::new("data/100-sentinel-2-items.parquet").unwrap();
let record_batch_reader = client.search_to_arrow(Default::default()).unwrap();
