# Derive Debug implementation on Snafu Errors that make pretty output

## What

The challenge: Error handling in Rust.  
The approach: Embrace `Result`s!  
The problem: It's not easy to give add nice contexts to errors.  
The solution: [Snafu](https://docs.rs/snafu)!

The challenge: Printing errors in CLI apps.  
The approach: Embrace `fn main() -> Result<(), Error>`!  
The problem: It prints using `Debug`, i.e., like `println!("{:?}", error)`.  
The solution: This crate!

## Usage

See example.

## Output

```console
$ cargo run --example simple -q -- foo
Error: Can't read file `foo`
        cause: No such file or directory (os error 2)
```

```console
$ cargo run --example simple -q -- foo
Error: Can't read file `foo`
        cause: No such file or directory (os error 2)
```
