STRUCT KUNIT_MEM_ASSERT(9)

✨ struct kunit_mem_assert — Kernel API Manual, bestie edition ✨

okay so picture this: you're deep in ./include/kunit/assert.h land, the Kernel API Manual is open, and you just need to know what a struct kunit_mem_assert is. Don't worry bestie, I got you 💖

---

🌸 NAME 🌸

struct kunit_mem_assert — it's an expectation/assertion that compares two memory blocks. literally that's the whole vibe. no cap.

---

🎀 SYNOPSIS 🎀

struct kunit_mem_assert {
    struct kunit_assert assert;
    const struct kunit_binary_assert_text *text;
    const void *left_value;
    const void *right_value;
    const size_t size;
};

🦋 Members 🦋

• assert — the parent of this type. every icon needs a parent, periodt.
• text — holds the textual representations of the operands and the comparator. it's giving receipts for your comparison 🔥
• left_value — the actual evaluated value of the expression in the left slot. main character of the left side 💅
• right_value — the actual evaluated value of the expression in the right slot. and the right side said "not me being compared" 🙈
• size — size of the memory block analysed, in bytes. number-crunching icon, fr fr 🍓

---

🧚 Description 🧚

so here's the tea ☕ — this struct represents an expectation/assertion that compares two memory blocks. yes, literally two blocks of memory, byte by byte, no drama (except the drama you're inherently creating by asserting things ✨).

for example, to expect that the first three bytes of foo is equal to the first three bytes of bar, you can use the expectation

KUNIT_EXPECT_MEMEQ(test, foo, bar, 3);

the way that 3 just... says "first three bytes, bestie" 😭 it ate and left no crumbs 👑
