Function terminal_cli::format_in_columns

pub fn format_in_columns<W: FmtWrite>(
    strings: &[&str], 
    width: u16, 
    spacing: u16, 
    new_line: &str, 
    write: &mut W
) -> Result<(), FmtError>

Formats the strings in autocomplete-style column notation. Fills the width of the entire line with a string plus the desired spacing characters. Preserves the ordering in columns.

Examples

let s = vec!["A1", "A2", "A3", "B1", "B2", "C1", "C2"];
let mut out = String::new();
format_in_columns(s.as_slice(), 26, 10, "\r\n", &mut out).unwrap();
println!("{}", out);

A1          B1          C2
A2          B2
A3          C1
