Rusqlite is an ergonomic wrapper for using SQLite from Rust. It attempts to expose an interface similar to rust-postgres. View the full API documentation.

extern crate rusqlite;
extern crate time;

use time::Timespec;
use rusqlite::Connection;

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

fn main() {
    let conn = Connection::open_in_memory().unwrap();

    conn.execute("CREATE TABLE person (
                  id              INTEGER PRIMARY KEY,
                  name            TEXT NOT NULL,
                  time_created    TEXT NOT NULL,
                  data            BLOB
                  )", &[]).unwrap();
    let me = Person {
        id: 0,
        name: "Steven".to_string(),
        time_created: time::get_time(),
        data: None
    };
    conn.execute("INSERT INTO person (name, time_created, data)
                  VALUES ($1, $2, $3)",
                 &[&me.name, &me.time_created, &me.data]).unwrap();

    let mut stmt = conn.prepare("SELECT id, name, time_created, data FROM person").unwrap();
    let mut person_iter = stmt.query_map(&[], |row| {
        Person {
            id: row.get(0),
            name: row.get(1),
            time_created: row.get(2),
            data: row.get(3)
        }
    }).unwrap();

    for person in person_iter {
        println!("Found person {:?}", person.unwrap());
    }
}

Optional Features

Rusqlite provides several features that are behind Cargo features. They are:

load_extension allows loading dynamic library-based SQLite extensions.
backup allows use of SQLite's online backup API.
functions allows you to load Rust closures into SQLite connections for use in queries.
trace allows hooks into SQLite's tracing and profiling APIs.
blob gives std::io::{Read, Write, Seek} access to SQL BLOBs.
