prost-serde-derive is a procedural macro for serializing/deserializing structs generated by [Prost] with [Serde].

How to use

When using [tonic-build], add type attribute to the structs/enums like following:

rust fn main() { tonic_build::configure() .type_attribute("some.proto.SomeStruct", "#[derive(prost_serde_derive::Deserialize, prost_serde_derive::Serialize)]") // Add following if you have to allow missing non-nullable fields when deserializing (will be filled with the default value) .type_attribute("some.proto.SomeStruct", "#[prost_serde_derive(use_default_for_missing_fields)]") // Add following if you have to allow deserializing even if there are type errors .type_attribute("some.proto.SomeStruct", "#[prost_serde_derive(omit_type_errors)]") // Serializing/deserializing Prost enumerations are also available .type_attribute("some.proto.SomeEnum", "#[derive(prost_serde_derive::Deserialize, prost_serde_derive::Serialize)]") .compile(...); }

Make sure to include base64 to your dependencies when bytes type is used in your proto.
