Remove deprecated Error::description and Error::cause #18

Closed AnderEnder closed 4 years ago

AnderEnder commented 4 years ago

Error::description has been documented as soft-deprecated since 1.27.0 (17 months ago). It is going to be hard-deprecated soon. Error::cause has been documented as deprecated since 1.27.0 .

This PR:

Removes all implementations of description
Replace cause with source
