More info about gRPC in documentation.

Making requests

use std::time::Duration;
use tonic::transport::Channel;
use qdrant_client::QdrantClient;
use qdrant_client::qdrant::ListCollectionsRequest;

#[tokio::main]
async fn main() {
    println!("Hello, qdrant!");

    let uri = "http://localhost:6334".parse().unwrap();
    let endpoint = Channel::builder(uri)
        .timeout(Duration::from_secs(5))
        .connect_timeout(Duration::from_secs(5))
        .keep_alive_while_idle(true);

    // `connect` is using the `Reconnect` network service internally to handle dropped connections
    let channel = endpoint.connect().await.unwrap(); // Unwrap in test only

    let mut client = QdrantClient::new(channel);
    let collections_list = client.collection_api.list(ListCollectionsRequest {}).await.unwrap();
    println!("Collection count {:?}", collections_list.into_inner().collections.len());
