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
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

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())
});
points.push(Point{
id: PointId::Num(4), vector: vec!(0.18, 0.01, 0.85, 0.80), payload: json!({"city": "New York"}).as_object().map(|m| m.to_owned())
});
points.push(Point{
id: PointId::Num(5), vector: vec!(0.24, 0.18, 0.22, 0.44), payload: json!({"city": "Beijing"}).as_object().map(|m| m.to_owned())
});
points.push(Point{
id: PointId::Num(6), vector: vec!(0.35, 0.08, 0.11, 0.44), payload: json!({"city": "Mumbai"}).as_object().map(|m| m.to_owned())
});
let r = client.upsert_points("my_test", points).await;
println!("The collection size is {}", client.collection_info("my_test").await);
// Retrieve #1
let ps = client.get_points("my_test", vec!(1, 2, 3, 4, 5, 6)).await;
println!("The 1-6 points are {:?}", ps);
// Retrieve Search
let q = vec![0.2, 0.1, 0.9, 0.7];
let r = client.search_points("my_test", q, 2).await;
println!("Search result points are {:?}", r);
// Delete
let r = client.delete_points("my_test", vec!(1, 4)).await;
println!("Delete points result is {:?}", r);
println!("The collection size is {}", client.collection_info("my_test").await);Add the following patches to cargo.toml and then you can use the qdrant_rest_client and tokio crates as regular dependencies.

To build it, you need to pass the Rust compiler flags as the above quick start.
RUSTFLAGS="--cfg wasmedge --cfg tokio_unstable" cargo build --target wasm32-wasi --release
Or, you can add to the .cargo/config.toml file.
[build]
target = "wasm32-wasi"
rustflags = ["--cfg", "wasmedge", "--cfg", "tokio_unstable"]
[target.wasm32-wasi]
runner = "wasmedge"
After that you can just cargo build and cargo run to build and run the application.
