Conversation
@TomAFrench do you know why the javascript tests are failing for every PR? |
Not sure. Seems like it started sometime this week so 🤷 |
I believe the issue was related to ts-node and the experimental feature we/everyone uses |

Description
Problem*
The
Trait
struct is quite large and was being cloned every timeget_trait
was called in the NodeResolver, which was somewhat often.Summary*
Stops the cloning of traits! The
Clone
derive is removed entirely and when needed for ownership reasons we either re-retrieve the trait by callingget_trait
again (which now returns a reference), or we temporarily take ownership of the trait's methods.Additional Context
