Function fs_extra::dir::copy_with_progress

pub fn copy_with_progress<P, Q, F>(
    from: P,
    to: Q,
    options: &CopyOptions,
    progress_handler: F
) -> Result<u64>where
    P: AsRef<Path>,
    Q: AsRef<Path>,
    F: FnMut(TransitProcess) -> TransitProcessResult,

Copies the directory contents from one place to another using recursive method, with information about progress. This function will also copy the permission bits of the original files to destination files (not for directories).

Errors

This function will return an error in the following situations, but is not limited to just these cases:

• This from path is not a directory.
• This from directory does not exist.
• Invalid folder name for from or to.
• The current process does not have the permission to access from or write to.

Example

extern crate fs_extra;
use fs_extra::dir::copy;

let options = CopyOptions::new(); //Initialize default values for CopyOptions
let handle = |process_info: TransitProcess|  {
    println!("{}", process_info.total_bytes);
    fs_extra::dir::TransitProcessResult::ContinueOrAbort
}
// copy source/dir1 to target/dir1
copy_with_progress("source/dir1", "target/dir1", &options, handle)?;
