proto
What is a .proto file?
text/plain
Proto files define Protocol Buffers schemas, Google's language-neutral interface definition language for serializing structured data. They declare typed messages, fields, and services that a compiler turns into efficient binary serialization code in many languages. They underpin gRPC and high-performance data interchange.
How to use a .proto file
Use an example proto file to test schema parsers, code generation across languages, and gRPC service or message-definition tooling.
