// NOTE: This test is to make sure that offset_of() doesn't read past the end of the "initialized" data.
// So we have to assume some things about the behavior of this class:
// - The chunk size is 4096 bytes.
// - A chunk is moved to the end when it's fully read from
// - A free chunk is used as-is, no new ones are allocated if one exists.
// First, fill exactly one chunk.

// First, fill exactly one chunk (in groups of 16 bytes).
for (size_t i = 0; i < AllocatingMemoryStream::CHUNK_SIZE / 16; ++i)
MUST(stream.write_until_depleted("AAAAAAAAAAAAAAAA"sv.bytes()));
// Then discard it all.
MUST(stream.discard(4096));
MUST(stream.discard(AllocatingMemoryStream::CHUNK_SIZE));
// Now we can write into this chunk again, knowing that it's initialized to all 'A's.
