WebApr 8, 2024 · Uint8Array. The Uint8Array typed array represents an array of 8-bit unsigned integers. The contents are initialized to 0. Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation). Uint8Array is a subclass of the hidden TypedArray class. http://duoduokou.com/cplusplus/50826658273582239076.html

WebFeb 7, 2015 · We can examine objects of any type as arrays of bytes. Objects of trivially-copyable types are the only C++ objects that may be safely copied with std::memcpy or serialized to/from binary files with std::ofstream::write ()/std::ifstream::read (). In general, a trivially copyable type is any type for which the underlying bytes can be copied to ... http://duoduokou.com/cplusplus/17497006232516450862.html

What you gain is one single assignment and memory access vs 4 assignments and memory accesses.
