Tips

• CEL expressions should always target the name of the fields in rust, not those of the message. For example, if a field is named type in protobuf, the output struct will have a field named r#type, and your cel expression should refer to it using this['r#type'], NOT this.type.

• If you use a BTreeMap in one of your fields, you need to add prost as a dependency and cannot rely on the re-export from this crate, due to a bug in prost’s macro output for BTreeMaps.
