pub fn parse_struct_prost_fields(
source: &str,
struct_name: &str,
) -> Result<Vec<ProtoField>, String>Expand description
Extract #[prost(..)] field declarations from one struct in Rust source
text, by scanning forward from each #[prost(..)] occurrence within the
struct’s brace-matched body to the field name it decorates. Deliberately
not a full Rust parser (no syn) — same tradeoff as parse_proto_message.
