1401: Make runtime and trap errors well defined r=syrusakbary a=MarkMcCaskey Resolves #1328 This PR goes through and gives explicit types for all the errors instead of using `Box<dyn Any + Send>` where possible. This gives users better insight into what the specific errors are and should help with debugging in the case of mistakes in our code. The remaining uses of `Box<dyn Any>` are due to the structure of our dependency graph -- this is probably solvable but it seems fine as is as all error types are now explicit and the remaining `Box<dyn Any>`s are either fully user controlled or not for end-user consumption. # Review - [x] Add a short description of the the change to the CHANGELOG.md file Co-authored-by: Mark McCaskey <mark@wasmer.io> |
