HOW

flatbuffers.Builder initializes with specified buffer capacity and tracks buffer offsets
flatbuffers.Builder.CreateString serializes null-terminated UTF-8 strings into the buffer and returns valid offset
flatbuffers.Builder.CreateByteVector serializes raw byte arrays and returns vector offset
flatbuffers.Builder.CreateSharedString deduplicates repeated strings by reusing previously serialized offsets
flatbuffers.Builder table serialization with StartObject, PrependInt32Slot, PrependFloat64Slot, and EndObject encodes vtables correctly
flatbuffers.Builder.Finish sets the root table offset at index 0 allowing Table deserialization
flatbuffers.Builder.FinishSizePrefixed prefixes the output buffer with the total buffer payload size
flatbuffers.Builder.Clear resets buffer offsets allowing the builder instance to be reused
flatbuffers.Builder enforces nesting rules by raising IsNestedError on nested StartObject calls
flatbuffers.Builder raises BuilderNotFinishedError when Output is called before Finish
flatbuffers.Builder raises IsNotNestedError when EndObject is called without an active StartObject
