Crate simple_error

Expand description

A simple error type backed by a string.

This crate provides a SimpleError type, which implements std::error::Error. The underlying is a String as the error message.

It should be used when all you care about is an error string.

It should not be used when you want to programmatically handle different kinds of an error.
