I have exactly the same problem, does anyone know how to solve it?

[padinsky]

Fix this issue by adding the protobuf-codec option to the features, like this:

pprof = { version = "0.11.1", features = ["flamegraph", "protobuf-codec"] }

But now it's telling me that the encode method does not exist in the profile object, does anyone know how to solve it?

I think this issue has already been fixed by https://github.com/tikv/pprof-rs/pull/208

In cargo projects, if you want to run an example, you can try cargo run --example exmaple_name.

Then you will get the tips about how to enable features for this example.

➜  pprof-rs git:(master) ✗ cargo run --example profile_proto_with_prost                         
error: target `profile_proto_with_prost` in package `pprof` requires the features: `prost-codec`
Consider enabling them by passing, e.g., `--features="prost-codec"`

Then:

➜  pprof-rs git:(master) ✗ cargo run --example profile_proto_with_protobuf_codec --features="protobuf-codec"
