You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: mod.rs
    path of file: ./repos/surrealdb/lib/benches/sdb_benches/sdk
    
    the code of the file until where you have to start completion: use criterion::{Criterion, Throughput};
use once_cell::sync::Lazy;
use serde::{Deseria
    
pub(super) async fn init(target: &str) {
	match target {
		#[cfg(feature = "kv-mem")]
		"sdk-mem" => {
			DB.connect("memory").await.unwrap();
		}
		#[cfg(feature = "kv-rocksdb")]
		"sdk-rocksdb" => {
			let path = format!(
				"rocksdb://sdk-rocksdb-{}.db",
				std::time::SystemTime::now()
					.duration_since(std::time::UNIX_EPOCH)
					.unwrap()
					.as_millis()
			);
			println!("\n### Using path: {} ###\n", path);
			DB.connect(&path).await.unwrap();
		}
		#[cfg(feature = "kv-fdb")]
		"sdk-fdb" => {
			DB.connect("fdb:///etc/foundationdb/fdb.cluster").await.unwrap();
			// Verify it can connect to the FDB cluster
			DB.health().await.expect("fdb cluster is unavailable");
		}
		#[cfg(feature = "protocol-ws")]
		"sdk-ws" => {
			DB.connect("ws://localhost:8000").await.unwrap();
		}
		_ => panic!("Unknown target: {}", target),
	};

	DB.use_ns("test").use_db("test").await.unwrap();
}
