Struct jammdb::KVPair

pub struct KVPair { /* fields omitted */ }

Key / Value Pair

You can use the key and value methods to access the underlying byte slices. The data is only valid for the life of the transaction, so make a copy if you want to keep it around longer than that.

Examples

use jammdb::{DB, Data};

let db = DB::open("my.db")?;
let mut tx = db.tx(false)?;
let bucket = tx.get_bucket("my-bucket")?;

// put a key / value pair into the bucket
bucket.put("my-key", "my-value")?;
if let Some(data) = bucket.get("my-key") {
    if let Data::KeyValue(kv) = &*data {
        let key: &[u8] = kv.key();
        let value: &[u8] = kv.value();
        assert_eq!(key, b"my-key");
        assert_eq!(value, b"my-value");
    }
}
