pub fn load_or_create_with<F>(path: &Path, create: F) -> Result<Vec<u8>>Expand description
Load a private regular file, or create it once from create.
Creation uses a temporary file beside path.
Its contents are synchronized before a no-clobber commit.
The containing directory is synchronized where supported.
A concurrent winner’s bytes are loaded and returned.
On Unix, existing files are restricted to mode 0600 before reading.
The final path is opened without following a symbolic link.
Other platforms retain the operating system’s inherited access controls.
§Errors
Returns a contextual error when the parent cannot be created. Non-regular entries and file operation failures are also reported.
