Function create_file 

pub fn create_file(
    path: &Path,
    target: WriteTarget,
) -> Result<File, WriteFailure>

Create or truncate path for writing, after the checks this module describes. Missing parent directories are created.

Errors

Returns WriteFailure::Directory when a parent directory cannot be created. Returns WriteFailure::File with PermissionDenied when the path resolves outside the recorded scope, or when a path component changed while the parent directories were created, and with the error of the open call when the final component became a symlink after the path was resolved (Unix) or the file cannot be created.
