Rust client for Qdrant vector search engine.

Installation

bash cargo add qdrant-client

Package is available in crates.io

Usage

Run Qdrant with enabled gRPC interface:

```bash

With env variable

docker run -p 6333:6333 -p 6334:6334 \ -e QDRANTSERVICEGRPC_PORT="6334" \ qdrant/qdrant ``` Or by updating the configuration file:

yaml service: grpc_port: 6334

More info about gRPC in documentation.

Making requests

```rust use std::time::Duration; use tonic::transport::Channel; use qdrantclient::QdrantClient; use qdrantclient::qdrant::ListCollectionsRequest;
