pub struct Colors<W> { /* private fields */ }
Expand description
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"
);

Sourcepub fn new(wrapped: W) -> Self
pub fn new(wrapped: W) -> Self
Creates a new Colors
instance with default spread of 3.0
,
frequency of 0.1
and seed valud of 0.0
Sourcepub fn configure(wrapped: W, spread: f64, frequency: f64, seed: f64) -> Self
pub fn configure(wrapped: W, spread: f64, frequency: f64, seed: f64) -> Self
Creates a more configurable instance with provided params
