Function ferris_says::say[][src]

pub fn say<W>(input: &[u8], max_width: usize, writer: &mut W) -> Result<()> where
    W: Write
Expand description

Print out Ferris saying something.

input is a slice of bytes that you want to be written out to somewhere

max_width is the maximum width of a line of text before it is wrapped

writer is anywhere that can be written to using the Writer trait like STDOUT or STDERR


The following bit of code will write the byte string to STDOUT

use ferris_says::*;
use std::io::{ stdout, BufWriter };

let stdout = stdout();
let out = b"Hello fellow Rustaceans!";
let width = 24;

let mut writer = BufWriter::new(stdout.lock());
say(out, width, &mut writer).unwrap();

This will print out:

< Hello fellow Rustaceans! >
        \) /  o o  \ (/
          '_   -   _'
          / '-----' \
