# 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)
```
