Method truncate

euralios_std/src/fs.rs:139–141

Sets the option for truncating a previous file. If a file is successfully opened with this option set it will truncate the file to 0 length if it already exists. The file must be opened with write access for truncate to work. # Examples ```no_run use std::fs::OpenOptions; let file = OpenOptions::new().write(true).truncate(true).open("foo.txt"); ```

(&mut self, truncate: bool)

    /// let file = OpenOptions::new().write(true).truncate(true).open("foo.txt");
    /// ```
    pub fn truncate(&mut self, truncate: bool) -> &mut OpenOptions {
        self.truncate = truncate; self
    }

    /// Sets the option for creating a new file.
    ///
