在async fn 中,可以使用 .await 来等待另一个实现 Future trait 的完成 与block_on 不同,.await不会阻塞当前线程,而是异步的等待 Future 的完成(如果该 Future 目前无法取得进展,就允许其他任务执行)use futures::executor::block_on; struct Song {} async fn learn_song() -> Song { Song {} } async...

Rust 1.39.0 已经发布。此版本的亮点包括 async/.await,对 match 守卫 by-move 绑定的共享引用,以及函数参数的属性。 async/.await 稳定 此版本 async/.await 特性已经稳定,这意味着现在可以定义 async 函数和块,并进行 .await 操作。 async 函数通过 async fn 引入,被调用时会返回一个 Future,该 Future 是...

异步编程:使用tokio或async-std库来实现异步编程,提高性能。 环境变量管理:使用dotenv库来管理 API 密钥等敏感信息。 开发步骤: 设计命令行参数结构,如输入文本、保存文件路径等。 使用clap或structopt库解析命令行参数。 集成GPT 模型 API,如 OpenAI GPT-3,设置 API 密钥和请求参数。
