Overview

Go code generator backend that produces FlatBuffers accessor structs and builder functions for the Go programming language.

Description

idl_gen_go.cpp implements the Go code generation backend for flatc. It generates Go structs with accessor methods that read directly from the underlying byte buffer, following Go naming conventions and package structure. The generated code depends on the github.com/google/flatbuffers/go runtime package for low-level buffer operations.

Usage

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