-/// without the Rust `std` library. It embeds a "kind" code, a message (static
-/// string only), and an optional chained cause (`std` only). The `kind` and
-/// `msg` fields can be accessed directly; cause can be accessed via
-/// `std::error::Error::cause` or `Error::take_cause`. Construction can only be
-/// done via `Error::new` or `Error::with_cause`.
