Expand description

Short form to compose Error values.

Here are few possible ways:

use crate::Error;
err_at!(ParseError, msg: format!("bad argument"));

use crate::Error;
err_at!(ParseError, std::io::read(buf));

use crate::Error;
err_at!(ParseError, std::fs::read(file_path), format!("read failed"));
