Fix Error::description() deprecation warning #28

Closed niklasf closed 3 years ago

niklasf commented 3 years ago

Deprecated since Rust 1.42.0, but does not require 1.42.0, because deprecation has been prepared in https://github.com/rust-lang/rust/pull/50163 by providing a default implementation.
