Rust language uses SQLite database

SQLite is a widely used lightweight database that hosts data through simple files without complex server configurations. As a result, it has become the preferred database for many desktop and mobile applications. In the Rust ecosystem, the rusqlitelibrary provides developers with a concise and effective way to manipulate SQLite databases. This article will comprehensively introduce how to use rusqlitefor database operations in Rust.

Start-up installation

Before we start, we need to bring rusqliteinto your Rust project. First, add rusqlitein the [dependencies]section of the Cargo.tomlfile:

[dependencies]
rusqlite = "0.25.3"

Once the addition is complete, execute cargo buildto download and compile the rusqlitelibrary and its dependencies.

Open and create a database

To manipulate an SQLite database, you first need to create a connection. Rusqliteprovides a Connectionobject to do this. The following example shows how to open an existing database file or create a new one:

use rusqlite::{Connection, Result};fn main() -> Result<()> {
    let conn = Connection::open("my_database.db")?;    // ， `conn` 
    // ...    Ok(())
}

Create table

With the Connectionobject, we can start creating the data table:

use rusqlite::{params, Connection, Result};fn main() -> Result<()> {
    let conn =…
