error-stack: Is there any way to clone error_stack::Result?

[jrmoulton]

Both T and E implement Clone but I can't clone a Report. Is there any way to do this?

[TimDiekmann]

No, a Report cannot be cloned as the errors inside of Report don't necessarily implement Clone. This would require a bound T: Clone on any operation on Report (i.e. all contexts and attachments would need to be Cloneable) but it's very common that errors don't implement Clone. As a very prominent example, std::io::Error does not implement Clone. Adding a Clone bound would imply that many errors would not work with error-stack anymore.

Interesting. that makes sense. Thanks for clearing that up!
