+    // Generic type read and write methods for Parcel:
+    //
+    // readData(T *value) will read a value from the Parcel.
+    // writeData(const T& value) will write a value to the Parcel.
+    //
+    // Our approach to parceling is based on two overloaded functions
+    // readData() and writeData() that generate parceling code for an
+    // object automatically based on its type. The code from templates are generated at
+    // compile time (if constexpr), and decomposes an object through a call graph matching
+    // recursive descent of the template typename.
+    //
+    // This approach unifies handling of complex objects,
+    // resulting in fewer lines of code, greater consistency,
+    // extensibility to nested types, efficiency (decisions made at compile time),
+    // and better code maintainability and optimization.
+    //
+    // Design decision: Incorporate the read and write code into Parcel rather than
+    // as a non-intrusive serializer that emits a byte stream, as we have
+    // active objects, alignment, legacy code, and historical idiosyncrasies.
+    //
+    // --- Overview
+    //
+    // Parceling is a way of serializing objects into a sequence of bytes for communication
+    // between processes, as part of marshaling data for remote procedure calls.
+    //
+    // The Parcel instance contains objects serialized as bytes, such as the following:
+    //
+    // 1) Ordinary primitive data such as int, float.
+    // 2) Established structured data such as String16, std::string.
+    // 3) Parcelables, which are C++ objects that derive from Parcelable (and thus have a
+    //    readFromParcel and writeToParcel method).  (Similar for Java)
+    // 4) A std::vector<> of such data.
+    // 5) Nullable objects contained in std::optional, std::unique_ptr, or std::shared_ptr.
+    //
+    // And active objects from the Android ecosystem such as:
+    // 6) File descriptors, base::unique_fd (kernel object handles)
+    // 7) Binder objects, sp<IBinder> (active Android RPC handles)
+    //
+    // Objects from (1) through (5) serialize into the mData buffer.
+    // Active objects (6) and (7) serialize into both mData and mObjects buffers.
+    //
+    // --- Data layout details
+    //
+    // Data is read or written to the parcel by recursively decomposing the type of the parameter
+    // type T through readData() and writeData() methods.
+    //
+    // We focus on writeData() here in our explanation of the data layout.
+    //
+    // 1) Alignment
+    // Implementation detail: Regardless of the parameter type, writeData() calls are designed
+    // to finish at a multiple of 4 bytes, the default alignment of the Parcel.
+    //
+    // Writes of single uint8_t, int8_t, enums based on types of size 1, char16_t, etc
+    // will result in 4 bytes being written.  The data is widened to int32 and then written;
+    // hence the position of the nonzero bytes depend on the native endianness of the CPU.
+    //
+    // Writes of primitive values with 8 byte size, double, int64_t, uint64_t,
+    // are stored with 4 byte alignment.  The ARM and x86/x64 permit unaligned reads
+    // and writes (albeit with potential latency/throughput penalty) which may or may
+    // not be observable unless the process is IO bound.
+    //
+    // 2) Parcelables
+    // Parcelables are detected by the type's base class, and implemented through calling
+    // into the Parcelable type's readFromParcel() or writeToParcel() methods.
+    // Historically, due to null object detection, a (int32_t) 1 is prepended to the data written.
+    // Parcelables must have a default constructor (i.e. one that takes no arguments).
+    //
+    // 3) Arrays
+    // Arrays of uint8_t and int8_t, and enums based on size 1 are written as
+    // a contiguous packed byte stream.  Hidden zero padding is applied at the end of the byte
+    // stream to make a multiple of 4 bytes (and prevent info leakage when writing).
+    //
+    // All other array writes can be conceptually thought of as recursively calling
+    // writeData on the individual elements (though may be implemented differently for speed).
+    // As discussed in (1), alignment rules are therefore applied for each element
+    // write (not as an aggregate whole), so the wire representation of data can be
+    // substantially larger.
+    //
+    // Historical Note:
+    // Because of element-wise alignment, CharVector and BoolVector are expanded
+    // element-wise into integers even though they could have been optimized to be packed
+    // just like uint8_t, int8_t (size 1 data).
+    //
+    // 3.1) Arrays accessed by the std::vector type.  This is the default for AIDL.
+    //
+    // 4) Nullables
+    // std::optional, std::unique_ptr, std::shared_ptr are all parceled identically
+    // (i.e. result in identical byte layout).
+    // The target of the std::optional, std::unique_ptr, or std::shared_ptr
+    // can either be a std::vector, String16, std::string, or a Parcelable.
+    //
+    // Detection of null relies on peeking the first int32 data and checking if the
+    // the peeked value is considered invalid for the object:
+    // (-1 for vectors, String16, std::string) (0 for Parcelables).  If the peeked value
+    // is invalid, then a null is returned.
+    //
+    // Application Note: When to use each nullable type:
+    //
+    // std::optional: Embeds the object T by value rather than creating a new instance
+    // by managed pointer as std::unique_ptr or std::shared_ptr.  This will save a malloc
+    // when creating an optional instance.
+    //
+    // Use of std::optionals by value can result in copies of the underlying value stored in it,
+    // so a std::move may be used to move in and move out (for example) a vector value into
+    // the std::optional or for the std::optional itself.
+    //
+    // std::unique_ptr, std::shared_ptr: These are preferred when the lifetime of the object is
+    // already managed by the application.  This reduces unnecessary copying of data
+    // especially when the calls are local in-proc (rather than via binder rpc).
+    //
+    // 5) StrongBinder (sp<IBinder>)
+    // StrongBinder objects are written regardless of null. When read, null StrongBinder values
+    // will be interpreted as UNKNOWN_ERROR if the type is a single argument <sp<T>>
+    // or in a vector argument <std::vector<sp<T>>. However, they will be read without an error
+    // if present in a std::optional, std::unique_ptr, or std::shared_ptr vector, e.g.
+    // <std::optional<std::vector<sp<T>>>.
+    //
+    // See AIDL annotation @Nullable, readStrongBinder(), and readNullableStrongBinder().
+    //
+    // Historical Note: writing a vector of StrongBinder objects <std::vector<sp<T>>
+    // containing a null will not cause an error. However reading such a vector will cause
+    // an error _and_ early termination of the read.
