If it exists, is there header file to include? This code results in a compilation error: int main() { byte b = 2; // error }

C++17 introduces the std::byte type. A library type that can (supposedly) be used to access raw memory, but stands separate from the character types and represents a mere lump of bits. So far so g...

C++ has a lot of types that vaguely describe the same thing. Assuming that we are compiling for an architecture where a byte is 8-bit, all of the following types are vaguely similar: std::byte std...

I'm trying to read a file in binary format into a std::vector<std::byte> std::ifstream fStream(fName, std::ios::binary); std::vector<std::byte> file_content((std::istreambuf_iterato...

std::byte is an abstraction that is supposed to provide a type safe(r) access to regions of memory in C++, starting with the new standard 17. However, it's declared this way according to http://en....

In CPP Reference it is stated that: std::byte is a distinct type that implements the concept of byte as specified in the C++ language definition. Like char and unsigned char, it can be used to acc...

std::byte is defined in C++17 as: enum class byte : unsigned char {}; I'm currently stuck at using C++14, and I wonder if I add the same definition in C++14 (in some non-std namespace, along with ...

Consider an unsigned char v that goes through a series of bit-wise operations with the result stored back to v. Under the hood, it is integer promoted once, undergoes a series of operations, and th...

I really like std::byte as a distinct type that implements the concept of byte as specified in the C++ language definition. What I don't like is the fact that modern C++ compilers will produce less...

The following code does not compile in C++20 #include <iostream> #include <cstddef> int main(){ std::byte b {65}; std::cout<<"byte: "<<b<<'\n';// Missing...

I'd like to use C++17's std::byte type if it's available, and fall back to using unsigned char if not, i.e. something along the lines of #include <cstddef> namespace my { #if SOMETHING usin...

I'm trying to learn new features/gimmicks of c++17, but then I got to std::byte and for some unknown reason I can't seem to be able to compile even most basic "hello world" type program with the ty...

C++17 introduced a new type, std::byte, so now we finally have a first-class citizen type to represent bytes in memory. Besides being a novelty in the standard, the C++ rules for object creation, s...

std::byte is a new type in C++17 which is made as enum class byte : unsigned char. This makes impossible to use it without appropriate conversion. So, I have made an alias for the vector of such ty...

Now that c++17 has std::byte, I was looking for a way to convert code that reads files to char into code that reads files into byte. A file contains bytes, not a bunch of integers. Then I read th...

C++ (and C) strict aliasing rules include that a char* and unsigned char* may alias any other pointer. AFAIK there is no analogous rule for uint8_t*. Thus my question: What are the aliasing rules...

Reading Herb Sutter's blog post about the most recent C++ standard meeting, it noticed that std::byte was added to C++17. As an initial reading, I have some concerns since it uses unsigned char so ...
