dircpy

一个跨平台的库，用于递归复制目录，并增加了一些便利功能。

 use dircpy::*;

 // Most basic example:
 copy_dir("src", "dest");

 // Simple builder example:
CopyBuilder::new("src", "dest")
  .run()
  .unwrap();

 // Copy recursively, only including certain files:
CopyBuilder::new("src", "dest")
  .overwrite_if_newer(true)
  .overwrite_if_size_differs(true)
  .with_include_filter(".txt")
  .with_include_filter(".csv")
  .run()
  .unwrap();
