Function std::fs::copy
[−]
[src]
pub fn copy<P: AsRef<Path>, Q: AsRef<Path>>(from: P, to: Q) -> Result<u64>
Copies the contents of one file to another. This function will also copy the permission bits of the original file to the destination file.
This function will overwrite the contents of to
`to`.
Note that if from
`fromand
` and to
`to` both point to the same file, then the file
will likely get truncated by this operation.
Errors
This function will return an error in the following situations, but is not limited to just these cases:
- The
from
`from` path is not a file - The
from
`from` file does not exist - The current process does not have the permission rights to access
from
`fromor write
` or writeto
`to`
Examples
fn main() { use std::fs; fn foo() -> std::io::Result<()> { try!(fs::copy("foo.txt", "bar.txt")); Ok(()) } }use std::fs; try!(fs::copy("foo.txt", "bar.txt"));
