pub fn reflink_or_copy<P: AsRef<Path>, Q: AsRef<Path>>(
from: P,
to: Q
) -> Result<Option<u64>>
Attempts to reflink a file. If the operation fails, a conventional copy operation is attempted as a fallback.
If the function reflinked a file, the return value will be `Ok(None)``.
If the function copied a file, the return value will be Ok(Some(written))
.
use reflink; match reflink::reflink_or_copy("src.txt", "dest.txt") { Ok(None) => println!("file has been reflinked"), Ok(Some(written)) => println!("file has been copied ({} bytes)", written), Err(e) => println!("an error occured: {:?}", e) }
