Functions

• borrow_as_box
  Borrows a mutable reference as Box for the lifespan of this function. Runs the given closure with the boxed value as a parameter. The closure is expected to return a boxed value, whose changes will be reflected on the mutable reference. Example:
• require
  Returns Some(()) if the condition is true, otherwise None. Useful in functions returning None on some condition: require(condition)?; And for functions returning Err on some condition: require(condition).ok_or_else(|| create_err())?;
• write_comma_separated
