However when I try to build I get the following error messages:
error[E0277]: the trait bound `Timestamp: prost::Message` is not satisfied

= help: the following other types implement trait `prost::Message`:

i64
u32
u64
f32
f64

This is with both rust 1.81 and 1.77.2, on Windows 10. I have tried using prost-wkt-types, setting the compile_well_known_types flag in the prost_build::Config, and setting various extern_path values to try and map the types correctly. What is frustrating is that I can see the #[derive(..., ::prost::Message)] on my instance of the Timestamp struct in the cargo registry!
Hello, I'm trying to use prost with a proto file that includes
google.protobuf.Timestamp
like so:I'm using prost-build with the following build script:
With these versions in my
