PlanetScale Serverless Driver for Rust™

Rust "version" of database-js. As stated in database-js it uses PlanetScale HTTP api for database queries. It will run perfectly run on Cloudflare Workers Or Vercel Edge Functions.

Usage

NOTE: Anyhow crate is required while using deserializer.

Examples

Connection and simple SQL execution

use planetscale_driver::PSConnection;

let conn = PSConnection::new(
  "<host>",
  "<user>",
  "<password>",
);
    
let res = conn.execute("SELECT 1").await.unwrap();

Rows deserialization into struct

As you can see, deserialization doesn't use field names (MAYBE IN FUTURE) so remember to write your structs correctly!

use planetscale_driver::{Database, Deserializer};

#[derive(Database, Debug)]
struct TestD {
  val: u32
}

// ...

let res = conn.execute("SELECT 1").await.unwrap();
let res: TestD = res.deserialize().unwrap();

println!("{:?}", res);

QueryBuilder

If you want to bind safely values into your query, you should use QueryBuilder

use planetscale_driver::QueryBuilder;

// ...

// note: values passed to .bind function must have trait ToString 
let id = 69;
let name = "420";

let res = QueryBuilder::new("INSERT INTO test(id, name) VALUES($0, \"$1\")")
  .bind(id)
  .bind(name)
  .execute(&conn)
  .await
  .unwrap();
