Go slices versus Rust Vec growth and reallocation
WHAT IT TESTS: understanding of dynamic-array internals. OUTLINE: both are a (pointer, length, capacity) triple over a heap buffer that reallocates and copies on growth, roughly doubling; key difference is Go slices share backing arrays and have no ownership…
WHAT IT TESTS: whether you know how growable arrays are laid out and grow, plus the ownership distinction. ANSWER OUTLINE: Both Go slices and Rust Vec<T> are a header of pointer, length, and capacity referencing a contiguous heap buffer. When an append exceeds capacity, each allocates a larger buffer (growth is amortized, commonly near doubling, smaller factor for large sizes), copies existing elements, and updates the pointer.
