proto_convert_derive
Automatically derive conversions between Protobuf-compiled prost types and your native Rust types.
Overview
proto_convert_derive is a procedural macro for bidirectional conversions between Protobuf-generated types (prost) and Rust structs. This reduces boilerplate and handles proto3's lack of required fields (which result in Option and lots .expect or if let Some in your code. This macro simply .expects types.
Key Features
- Automatically implements
From<Proto>for Rust types and vice versa. - Supports collections like
Vec<Proto> - Direct mapping for primitive types.
- Unwraps optional fields with
.expect. - Supports newtype wrappers.
- Customizable Protobuf module (default is
protovia#[proto(module = "your_module")]). - Ignore individual fields
#[proto(ignore)]
