Atomic file operations handler

Implementations§

Source§

impl AtomicFileOperations

Source

pub fn new() -> Self

Create new atomic file operations instance

Source

pub fn atomic_copy_file( &self, source: &Path, destination: &Path, ) -> NativeResult<()>

Perform atomic file copy from source to destination

Requirements:

  • Source must exist and be a file (not directory)
  • Destination must not exist (overwrite protection)
  • Uses temporary file + rename for atomicity
  • Full fsync discipline for crash safety
  • Cleanup on any failure
§Failing TDD Tests Expected:
  • test_atomic_copy_file_to_new_location
  • test_atomic_copy_rejects_directory
  • test_atomic_copy_overwrite_protection
  • test_atomic_copy_crash_safety_simulation
