castor 使用 LMDB 和 kv 提供基于内容可寻址的存储

use castor::{Config, Store, Blake2s, Txn, Token};

fn main() -> Result<(), kv::Error> {
    let cfg: Config<Blake2s> = Store::config("/tmp/castor-example");
    let mut store: Store<Blake2s> = Store::new(cfg)?;
    let bucket: kv::Bucket<Token<Blake2s>, &str> = store.bucket(None)?;
    let token = store.with_write_txn(|mut txn| {
        txn.put(&bucket, "testing")
    })?;
    let x = store.with_read_txn(move |txn| {
        let value = txn.fetch(&bucket, token)?;
        Ok(String::from(value))
    })?;
    assert_eq!(x, "testing");
    Ok(())
}
