The first contains no consecutive repeated elements.

To make m2 of the type Vec> (like m3), you should clone m1 instead of taking a reference to it. [1,2,3];

Because Vec::from_raw_parts expects three parameters, a pointer, a size and a capacity, we either have to keep track of the capacity as well somehow, or we use Vec's shrink_to_fit before passing the pointer and length to the C function. (vec2, [2, 3]); assert_eq! (1 answer) Closed 2 years ago.

The second contains all the duplicates in no specified order.If the slice is sorted, the first returned slice contains no duplicates.This function will panic if the two slices have different lengths.Rust enforces that there can only be one mutable reference with no [0, 1, 2]; See The current algorithm is an adaptive, iterative merge sort inspired by
