Crate gproxy_protocol_macros 

Builders for protocol structs with required arguments and optional setters.

Derive Macros

DeclaredFields

Rebuilds the same wire type using declared fields, recursively dropping extension bags without reading, cloning, or serializing them. Mark a bag with #[declared(extension)]; #[serde(flatten)] rest is also recognized. Formal JSON fields are preserved. This derive does not change serde behavior. An alternate protocol crate path can be supplied with #[declared(crate = "path")]. #[declared(bound = "T: path::DeclaredFields")] replaces inferred formal-field bounds, for example for mutually recursive generic types. Existing where clauses and extension-field Default bounds are retained.

WireBuilder

Generates Type::builder(required_fields...) and a TypeBuilder.
