Options

• create_always

  Always creates a new file and opens it. If the file already exists, the old file content will be discarded and the file is treated as a new empty file.

• create_new

  Only creates a file and opens it when it does not exist. If the file already exists, the call fails with BasicError::already_exists.

• open_always

  Always opens a file. If the file already exists, the file will be open with its data preserved, if the file does not exist, it will be created and opened.

• open_existing

  Only opens a file when it does exists. If the file does not exist, the call fails with BasicError::not_found.

• open_existing_as_new

  Only opens a file when it does exists, and discards the file data so the file is treated as a new file.
