sewup = { features = [“kv”] }

use sewup::kv::Store;
use sewup::types::{Raw, Row};

let mut store = Store::new().unwrap();
let mut bucket = store.bucket::<Raw, Raw>("default").unwrap();

// Set testing = 123
bucket.set(b"test".into(), b"123".into());

// Set store with specific types
let mut bucket2 = store.bucket::<Raw, Row>("bucket2").unwrap();
bucket2.set(b"long".into(), "Testing".to_string().into());
