Motivation

Issue #343 as well as some Discord discussions around May 5th—7th 2020 contain motivation for the PR.

Solution

  • Added metadata field to the Status struct, like in the Response struct
    • If the provided metadata contains any headers with names reserved either by the gRPC spec or by Status fields (e.g. grpc-status-details-bin), they will be ignored.
  • Updated existing Status constructors and conversions to support metadata
  • Added Status constructors with metadata only or also with details
  • Updated Debug and Display implementations for Status to support the new field
  • Added an integration test for the functionality
  • This change should be backward compatible

Looks great, one small nit and we can merge. I can try to get a release out today.

@LucioFranco Are you good with the constrictor naming? with_details_and_metadata? It's a little bit long, but explicit :)

@dvshur yeah, I think for now it is fine, I suspect in the future we might refactor but its a code path that is not hit often enough to really require good ergonomics.
