Description

This crate allows you to replace all expect(…) with expecto_patronum(…) which works in the same way but also prints a beautiful patronus with your panic message. Patronus animal depends on the message you provide.

Examples

Simple usage example:

use expecto_patronum::prelude::*;

let x = Some("Harry Potter");
assert_eq!(x.expecto_patronum("No dementors here"), "Harry Potter");

use expecto_patronum::prelude::*;

let x: Option<&str> = None;
x.expecto_patronum("No dementors here"); // panics with `No dementors here` and casts a patronus

Output of the last example:

thread 'main' panicked at '
 _,
<\ `.
  `. `~'^----.._            _
   `. ,    _,  `.`-.       ' )
   , ),'-~'(   / ` .`-.___,-'
  ( /;      `'\,    `
  _/'       _//       `.
 ' "       ' "       ' `
No dementors here
'

Try this out

You can run

cargo run --example summon

And enter any line you want to get an example of generated animal.
