Function sgx_tstd::sgxfs::copy

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 overwrite the contents of to.

Note that if from and to both point to the same file, then the file will likely get truncated by this operation.

On success, the total number of bytes copied is returned.
