Pointers don't hold anything, they just point.

It points, but there's no information about what it's pointing to until it's cast to a different pointer type.

I wrote a C# library that pushes application-layer authorization down into the EFCore DbContext.

why doesn't this work?? I'm moving the vector to deal with the unique_ptrs inside the struct that make it move only, but I keep getting complaints about
>error: static assertion failed: result type must be constructible from input type
and I don't understand what it needs me to do

#include <iostream>
#include <memory>
#include <vector>

class MyClass {
public:
    struct Info {
        int a;
        std::unique_ptr<int> b;
    };
    
    void replace_infos(std::vector<Info> new_infos) {
        infos = std::move(new_infos);
    }
    
    std::vector<Info> infos;
};

int main()
{
    MyClass myClass;
    
    myClass.replace_infos({
        { 5, nullptr },
        { 6, nullptr },
    });

    return 0;
}

>>106597094
Java NIO was breddy gud but C# solved multithreaded I/O with async/await.

>>106597817
you need to initialize myClass

>>106597919
but it's initialized right there, first line in main. I wouldn't be able to call the function if it wasn't initialized

>>106597817

    MyClass myClass;
    
    std::vector<MyClass::Info> infos;
    MyClass::Info info;
    info = {
        .a = 5,
        .b = nullptr
    };
    infos.push_back(std::move(info));
    info = {
        .a = 6,
        .b = nullptr
    };
    infos.push_back(std::move(info));
    myClass.replace_infos(std::move(infos));

okay I made it work, I guess initializer lists cannot be moved for whatever reason (but it lets me move my 'info' object constructed from an initializer list ???). anyways is there a way to streamline this so that it's not so overlay verbose?

resolving all the minutiae of this towards getting a decently robust prototype was more finnicky than i expected

i started with making lock-free alloc-free multithreaded logging, which worked well on a single producer single consumer model
then i thought i might try to expand to multi producer multi consumer tinkering, then i decided to create my own lock free, alloc free multithreaded general purpose event queue that supports work stealing and fiber scheduling, and i think itll be nice when it's done

STOP following clean code blindly
QUIT creating millions of shallow classes for one line functions

>>106599857
Excuse me Mr. Anon- how do I put my code in the format you just did there?

>>106599857
I'm doing something like this in my current project:

#ifdef EXAMPLE_DEBUG
#define debug_log(fmt, ...) _debug_log(fmt, ##__VA_ARGS__)
#else
#define debug_log(fmt, ...) _disabled_debug_log(fmt, ##__VA_ARGS__)
#endif

Basically I call

debug_log()

exactly like

printf()

.
In the release build,

_disabled_debug_log()

is just a constexpr function that returns 0 immediately (because printf usually returns its length).
In the debug build, by default

_debug_log()

just prints to stderr, but it does so through a callback function that can be set to something else in case I want to handle the debug log differently (project is a shared library, so I might want to handle it differently in different programs that use the library).

So, yesterday I had this...

void
print_unchecked(char const* const ptr, usize const len) noexcept;

template <usize N>
void
print_unchecked(char const (&ptr)[N]) noexcept
{
    print_unchecked(ptr, N - 1);
}

void
print_unchecked(u64 const number) noexcept;

void
flush() noexcept;

template <typename... Args>
void
print(Args&&... args) noexcept
{
    (print_unchecked(static_cast<Args&&>(args)), ...);
    flush();
}

Hmmm, lets see...

template <typename... Args>
void
debug(Args&&... args) noexcept
{
#ifndef NDEBUG
    print("[DEBUG] ", static_cast<Args&&>(args)...);
#endif
}

That was very hard and took me HOURS of thinking how to solve in my overcomplicated setup of cepples with Make as is done by true luddites, enough programming for today, I'm exhausted from writing this trivial function that just works, bye!

In Cshart this is just

}

What does it mean for a pointer to hold an address? Don't you need more memory cells the larger the pointee? So, shouldn't pointers to double or large structs hold more than one address? In fact, can't void pointers be arbitrarily large?

Run a

printf("%zu\n", sizeof(<pointer_name>));

On all of your pointers. Assuming you're on 64bit architecture, the pointer (which only holds an address location in memory; nothing else) should always be 8 bytes.

>a guy that can find your mom
STACK OVERFLOW

>>106602011
I see where you are confused. Addresses contain 1 byte values. For a double that is 8 bytes wide, a double pointer contains the address where the double value STARTS in memory. e.g. for a double pointer that points to address 0x01 the compiler (knowing this is a double because of the pointer type) will load 0x01 TO 0x08 (a total of 8 addresses read) and treat it as double.
This isn't done like you imagine by reading 1 byte at a time, but by reading into a register that is 8 bytes wide using one instruction e.g. mov fp_reg, [mem]
