Macro table_formatter::fmt

macro_rules! fmt {
    () => { ... };
    ($func: expr) => { ... };
    ($($func: expr),+ $(,)?) => { ... };
}

This macro is used to wrap those formatters.

Since the formatters use both closures and functions, and that two types are not capable with each other, the lib uses a enum(FormatterFunc) to combine them together.

This macro will automatically convert any function pointers and closures to a Rc<Box<dyn Fn(...) -> ...>>, generating FormatterFunc::Boxed.

You can just use it as the way you use the vec! macro.

let (r, g, b) = (100, 20, 70);
fmt!(Colorize::blue, move |s| s.truecolor(r, g, b));
