1///# Error
2/// Logs errors and then kills the program with exit code 1.
3///
4///## ⚠WARNING⚠
5/// `error!` creates a hook for `panic!` which also silences the typical error message.
6/// This hook applies to ALL uses of panic once `error!` has been invoked.
7/// The `panic!` macro will be affected for the rest of your program's runtime.
8///
9/// Examples
10///
11/// Kill program
12/// ```no_run
13///# use info_utils::prelude::*;
14///# fn main()  {
15///     // Something is happening..
16///     // Uh oh, an error has occurred.
17///     error!("Something unrecoverable went wrong!");
18///# }
19///```
20///
21///Kill thread
22/// ```rust
23///# use std::thread;
24///# use info_utils::prelude::*;
25///# fn main() {
26/// thread::spawn(|| {
27///     // Do a calculation
28///     // Oh no, an error happened and we need to kill the thread!
29///     error!("Noncritical error, thread aborting");
30/// }).join().eval_or_default();
31///# }
32///```
