Rust 中,dotenvcrate 用来读取环境变量。取得环境变量后,我们将其作为静态或者惰性值来使用,静态或者惰性值相关的 crate 有lazy_static和once_cell等,都很简单易用。此示例中,我们使用lazy_static。 创建.env,添加读取相关 crate 增加这 2 个 crate,并且在backend目录创建.env文件。 代码语言:javascript 代码运行次数...

* Run the functions in the `tasks` collection in series, each one running once * the previous function has completed. If any functions in the series pass an * error to its callback, no more functions are run, and `callback` is
One way around the above problems is to revert to the old TPL upon whichasync/awaitis based. You’re going to use TPL directly, but only once to start the chain of async method calls (and to start a new thread right away). Somewhere down the line, the TPL will be used directly aga...
