Asynchronous handle for rusqlite library.

Usage

use rusqlite::{params, Result};
use tokio_rusqlite::Connection;

#[derive(Debug)]
struct Person {
    id: i32,
    name: String,
    data: Option<Vec<u8>>,
}

#[tokio::main]
async fn main() -> Result<()> {
    let conn = Connection::open_in_memory().await?;

    let people = conn
        .call(|conn| {
            conn.execute(
                "CREATE TABLE person (
                    id    INTEGER PRIMARY KEY,
                    name  TEXT NOT NULL,

                )",
                [],
            )?;

            let steven = Person {
                id: 1,
                name: "Steven".to_string(),
                data: None,
            };

            conn.execute(

                .collect::<Result<Vec<Person>, rusqlite::Error>>()?;
