Overview

Generated Rust code for the canonical Monster sample schema, demonstrating FlatBuffers Rust code generation.

Description

monster_generated.rs is the Rust source generated by flatc from the Monster tutorial schema. It defines zero-copy accessor structs and builder helpers for Monster, Weapon, and Vec3 using Rust lifetime annotations for safe buffer access. This file is included in the vendored tree as a reference for the Rust code generation backend.

Usage

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