/// Vec may use any or none of the following strategies,

/// The last case warrants some attention. It is an optimization that in many cases reduces peak memory
/// consumption and improves cache locality. But when big, short-lived allocations are created,
/// only a small fraction of their items get collected, no further use is made of the spare capacity
/// and the resulting `Vec` is moved into a longer-lived structure, then this can lead to the large
/// allocations having their lifetimes unnecessarily extended which can result in increased memory
/// footprint.
