Retrieves detailed information about a specific store by name. Returns metadata including dimensions, size, and configured indices.

use ahnlich_client_rs::db::DbClient;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let db_client = DbClient::new("127.0.0.1:1369".to_string()).await?;

    let tracing_id: Option<String> = None;

    let store_info = db_client
        .get_store("my_store".to_string(), tracing_id)
        .await?;

    println!("Store name: {}", store_info.name);
    println!("Number of entries: {}", store_info.len);
    println!("Size in bytes: {}", store_info.size_in_bytes);
    println!("Dimension: {}", store_info.dimension);
    println!("Predicate indices: {:?}", store_info.predicate_indices);
    println!("Non-linear indices: {:?}", store_info.non_linear_indices);

    Ok(())
}

Parameters

• store: String — The name of the store to retrieve.

• tracing_id: Option<String> — Optional trace context for observability.

Returns

• StoreInfo — Detailed information about the store.

• AhnlichError — If the store does not exist or the request fails.

StoreInfo Fields

Field	Type	Description
name	String	Store name
len	u64	Number of entries in the store
size_in_bytes	u64	Total size of the store in bytes
dimension	u32	Vector dimension
predicate_indices	Vec<String>	List of indexed predicate keys
non_linear_indices	Vec<NonLinearIndex>	List of non-linear algorithm indices

Behavior

• Sends a request to retrieve store metadata by name.

• Returns an error if the store does not exist.

• Useful for inspecting store configuration before operations.

Notes

• Use list_stores to get information about all stores
• The size_in_bytes field is useful for monitoring memory usage
