是否有在nim-lang中实现SQLite3扩展的示例？

import os
import sqlite3

# 定义SQLite3数据库文件路径
const dbPath = "example.db"

# 创建SQLite3数据库连接
var conn: sqlite3.DB
if not conn.open(dbPath):
    echo "Failed to open database:", conn.errmsg
    quit(1)

# 创建表格
if conn.exec("CREATE TABLE IF NOT EXISTS users (id INTEGER PRIMARY KEY, name TEXT, age INTEGER)") != SQLITE_OK:
    echo "Failed to create table:", conn.errmsg
    quit(1)

# 插入数据
if conn.exec("INSERT INTO users (name, age) VALUES ('John', 25)") != SQLITE_OK:
    echo "Failed to insert data:", conn.errmsg
    quit(1)

# 查询数据
var stmt: sqlite3.Stmt
if conn.prepare("SELECT * FROM users") != SQLITE_OK:
    echo "Failed to prepare statement:", conn.errmsg
    quit(1)

while conn.step(stmt) == SQLITE_ROW:
    let id = conn.columnInt(stmt, 0)
    let name = conn.columnText(stmt, 1)
    let age = conn.columnInt(stmt, 2)
    echo "ID:", id, " Name:", name, " Age:", age

# 关闭数据库连接
conn.close()
