Expand description
Backports changes to the Error
trait to
versions of Rust lacking them.
It is recommended to always call these methods explicitly so that it is easy to replace usages of this trait when you start supporting a newer version of Rust.
ErrorCompat::backtrace(&error); // Recommended
error.backtrace(); // Discouraged
