Macro padded_width_of

macro_rules! padded_width_of {
    ($($t:tt)*) => { ... };
}

Compute the width of multiple items while optionally declaring the options for each item.

let alpha = 0;
let beta = 1;
let gamma = 100;

let width = smart_display::padded_width_of!(
    alpha, // use the default options
    beta => width(2), // use the specified options
    gamma => width(2) sign_plus(true), // use multiple options
);
assert_eq!(width, 7);

let formatted = format!("{alpha}{beta:2}{gamma:+2}");
assert_eq!(formatted.len(), width);

Supported options are:

Option	Method called
fill(char)	FormatterOptions::with_fill
sign_plus(bool)	FormatterOptions::with_sign_plus
sign_minus(bool)	FormatterOptions::with_sign_minus
align(Alignment)	FormatterOptions::with_align
width(usize)	FormatterOptions::with_width
precision(usize)	FormatterOptions::with_precision
alternate(bool)	FormatterOptions::with_alternate
sign_aware_zero_pad(bool)	FormatterOptions::with_sign_aware_zero_pad

If there are future additions to FormatterOptions, they will be added to this macro as well.

Options may be provided in any order and will be called in the order they are provided. The ordering matters if providing both sign_plus and sign_minus.
