Overview

Go gRPC stub generator that emits client and server service interfaces using FlatBuffers as the wire format.

Description

go_generator.cc implements the Go gRPC stub generation logic. It generates Go source files containing service interfaces, client structs, and server handler registrations that use FlatBuffers for message serialization instead of Protocol Buffers. The generated code integrates with the standard google.golang.org/grpc package and uses the FlatBuffers Go runtime for marshaling and unmarshaling.

Usage

Vendored dependency used internally by MNN for model serialization. Not directly imported by end users.
