Enum std::old_io::FileModeUnstable

pub enum FileMode {
    Open,
    Append,
    Truncate,
}

A mode specifies how a file should be opened or created. These modes are passed to File::open_mode and are used to control where the file is positioned when it is initially opened.

Variants

Open	Opens a file positioned at the beginning.
Append	Opens a file positioned at EOF.
Truncate	Opens a file, truncating it if it already exists.
