checkEmptyAfterMove()

void xrpl::test::BufferTest::checkEmptyAfterMove ( Buffer const & buf )

static

Check the state Buffer documents for a moved-from buffer: "the other buffer is reset", i.e.

empty and sane.

Zeroing the size is not incidental tidiness. Moving the member unique_ptr nulls the data pointer whether Buffer wants it or not, so a moved-from buffer that kept its old size would lie about itself everywhere: alloc() would take its n == size_ early-out and hand back a null pointer while still reporting the old size, fill() would run std::fill_n over a null pointer, and the Slice conversion would publish {nullptr, oldSize} to callers. A moved-from Buffer has to be a usable empty Buffer rather than a landmine, which is why the tests below assert this state instead of treating a moved-from buffer as untouchable.
