This error indicates a violation of one of Rust's orphan rules for trait implementations. The rule prohibits any implementation of a foreign trait (a trait defined in another crate) where

• the type that is implementing the trait is foreign
• all of the parameters being passed to the trait (if there are any) are also foreign.
