The key requirements for this unofficial client are two folds:
- Compiles into Wasm and runs under the WasmEdge Runtime.
- Supports basic CRUD operations for vector collections and points.
- Supports TLS for remotely installed Qdrant databases.
Install WasmEdge and Rust tools.
curl -sSf https://raw.githubusercontent.com/WasmEdge/WasmEdge/master/utils/install.sh | bash -s -- --plugins wasmedge_rustls
source $HOME/.wasmedge/env
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustup target add wasm32-wasi
Start a Qdrant instance in Docker using the quick start guide.
mkdir qdrant_storage
docker run -p 6333:6333 -p 6334:6334 \
-v $(pwd)/qdrant_storage:/qdrant/storage:z \
qdrant/qdrant

in this repo.

Here is the code from the examples/src/main.rs to show how to do CRUD operations.
// Create
let r = client.create_collection("my_test", 4).await;
// Insert / Update
let mut points = Vec::<Point>::new();
points.push(Point{
id: PointId::Num(1), vector: vec!(0.05, 0.61, 0.76, 0.74), payload: json!({"city": "Berlin"}).as_object().map(|m| m.to_owned())
});
points.push(Point{
id: PointId::Num(2), vector: vec!(0.19, 0.81, 0.75, 0.11), payload: json!({"city": "London"}).as_object().map(|m| m.to_owned())
});
points.push(Point{
id: PointId::Num(3), vector: vec!(0.36, 0.55, 0.47, 0.94), payload: json!({"city": "Moscow"}).as_object().map(|m| m.to_owned())
});
