You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: justify.rs
    path of file: ./repos/tabled/tabled/src/settings/width
    
    the code of the file until where you have to start completion: //! This module contains [`Justify`] structure, used to set an exact width to each column.

use crate::{
    grid::config::ColoredConfig,
    grid::records::{ExactRecords, IntoRecords, PeekableRecords, Records, RecordsMut},
    settings::{
        measurement::{Max, Measurement, Min},
        CellOption, Tabl
    
    fn change(self, records: &mut R, cfg: &mut ColoredConfig, _: &mut D) {
        let width = self.width.measure(&*records, cfg);

        let count_rows = records.count_rows();
        let count_columns = records.count_columns();

        for row in 0..count_rows {
            for col in 0..count_columns {
                let pos = (row, col).into();
                CellOption::change(Width::increase(width), records, cfg, pos);
                CellOption::change(Width::truncate(width), records, cfg, pos);
            }
        }
    }
