Kyval

Kyval is a simple key-value store based on LibSQL. This project is a fork of Kyval Rust, originally created by Christian Llontop. By utilizing LibSQL, Kyval offers a lightweight and flexible alternative for simple data storage needs.

Main changes: The primary difference between Kyval and the original Kyval Rust is the use of LibSQL as the database backend, replacing SQLite. This change enables Kyval to have improved flexibility in data storage.

Usage

Instalation

cargo add kyval

Interacting with Store

use kyval::Kyval;

#[tokio::main]
async fn main() {

    let kyval_store = KyvalStoreBuilder::new()
        .uri(":memory:")
        .table_name("kv_store")
        .build()
        .await.unwrap();

    let keyv = Kyval::try_new(kyval_store).await.unwrap();

    kyval.set("number", 42).await.unwrap();
    kyval.set("number", 10).await.unwrap();
    kyval.set("array", vec!["hola", "test"]).await.unwrap();
    kyval.set("string", "life long").await.unwrap();

    match kyval.get("number").await.unwrap() {
        Some(number) => {
            let number: i32 = serde_json::from_value(number).unwrap();
            assert_eq!(number, 10);
        }
        None => assert!(false),
    }

    match kyval.get("string").await.unwrap() {
        Some(string) => {
            let string: String = serde_json::from_value(string).unwrap();
            assert_eq!(string, "life long");
        }
        None => assert!(false),
    }

    match kyval.get("array").await.unwrap() {
        Some(array) => {
            let array: Vec<String> = serde_json::from_value(array).unwrap();
            assert_eq!(array, vec!["hola".to_string(), "test".to_string()])
        }
        None => assert!(false),
    }

    match kyval.remove_many(&["number", "string"]).await {
        Ok(_) => {}
        Err(_) => assert!(false),
    }
}
