Function format_strings

pub fn format_strings(
    vec_col: &[&str],
    lower_column_width: usize,
    upper_column_width: usize,
    sigfig: i64,
    preserve_scientific: bool,
    max_decimal_width: usize,
) -> Vec<String>

Formats a column of strings with consistent width and significant figures.

This is the main formatting function that processes an entire column of data. It applies significant figure formatting to numeric values, handles NA values, and ensures all strings fit within the specified width constraints.

Arguments

• vec_col - Vector of string references representing the column data
• lower_column_width - Minimum column width
• upper_column_width - Maximum column width
• sigfig - Number of significant figures for numeric values
• preserve_scientific - Whether to preserve scientific notation
• max_decimal_width - Maximum width for decimal places

Returns

A vector of formatted strings with consistent width and formatting.

Examples

use tidy_viewer_core::datatype::format_strings;

let data = vec!["123.456", "NA", "-42.1", "hello"];
let formatted = format_strings(&data, 2, 20, 3, false, 13);

// All formatted strings will have consistent width and formatting
assert_eq!(formatted.len(), 4);
