通过调用 env::current_dir 获取当前工作目录,然后通过 fs::read_dir 读取目录中的每个条目,通过 DirEntry::path 提取条目路径,以及通过通过 fs::Metadata 获取条目元数据。Metadata::modified 返回条目自上次更改以来的运行时间 SystemTime::elapsed。Duration::as_secs 将时间转换为秒,并与 24 小时(24 * 60 * ...

【功能】指派cargo,在编译过程中,在$OUT_DIR文件夹内(即,target\debug或target\release),创建一个指向【C ABI动态链接库(文件)】的【符号链接】。 【例程】至于如何编写该build.rs程序,可参考: use ::std::{env, fs, os, path::{Path, PathBuf}};fn main() { let out_dir = env::var("OUT_DIR"...
