WebSince the compiler cannot prove that you are borrowing disjoint parts of a vector, or that a function only borrows certain parts of a struct and not the whole object, it forces you to borrow the whole vector/struct to be safe. In the case of vectors, one could easily prove disjoint borrows when using constant vector indexes. WebThe vector will be able to hold at least capacity elements without reallocating. This method is allowed to allocate for more elements than capacity. If capacity is 0, the vector will not allocate. It is important to note that although the returned vector has the minimum capacity specified, the vector will have a zero length.
