Milvus Rust SDK

Rust SDK for Milvus.

This is still in progress, but should be already to run in your production environemnt, we are actively looking for maintainers of this repo

Get Started

Add the SDK into your project:

cargo add milvus-sdk-rust

Connect to milvus service and create collection:

#[tokio::main]
async fn main() -> Result<(), Error> {
    const URL: &str = "http://localhost:19530";

    let client = Client::new(URL).await?;

    let schema =
        CollectionSchemaBuilder::new("hello_milvus", "a guide example for milvus rust SDK")
            .add_field(FieldSchema::new_primary_int64(
                "id",
                "primary key field",
                true,
            ))
            .add_field(FieldSchema::new_float_vector(
                DEFAULT_VEC_FIELD,
                "feature field",
                256,
            ))
            .build()?;
    let collection = client.create_collection(schema.clone(), None).await?;
    Ok(())
}
