Struct rainbowcoat::Colors

pub struct Colors<W> { /* fields omitted */ }

Colors writable type characters with the ascii rainbow

You can use this any type that requires a io::Write type

examples

Write direcly to stdout

use std::io::{self, Write};
write!(
  &mut rainbowcoat::Colors::new(io::stdout()),
  "hello rainbow"
);

A convenience function makes this common case even easier

use std::io::Write;
write!(
  &mut rainbowcoat::stdout(),
  "hello rainbow"
);
