Description

cannot convert Any to Message

the trait bound `my::Message: prost::name::Name` is not satisfied
the following other types implement trait `prost::name::Name`:
  prost_types::protobuf::Any
  prost_types::protobuf::Duration
  prost_types::protobuf::Timestamp
lib.rs(59, 22): required by a bound in `prost_types::<impl prost_types::protobuf::Any>::to_msg`

So this is as intended, for now only certain types have the implementation, but we need to implement #926 to fully take advantage of this.

[tarcieri]

For now you can impl the Name trait by hand on my::Message

Thanks for your answers.
But I have one more question, is it possible to deserialize a known struct my::Message from any.value or just a Vec<u8>?

[tarcieri]

@c0mm4nd you can use Any::to_msg with any message type which impls Name, which will also validate the type URL is correct for the message type

[tarcieri]

Also this should probably be closed in favor of #926
