Overview

Lobster code generator backend that produces FlatBuffers accessor functions for the Lobster programming language.

Description

idl_gen_lobster.cpp implements the Lobster code generation backend for flatc. Lobster is a statically-typed game programming language, and this generator emits Lobster functions and classes that provide zero-copy read access to FlatBuffer data. The generated code integrates with Lobster's built-in FlatBuffers runtime support.

Usage

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