array is part of its type, which means that [u8; 3] and [u8; 4] are considered two different types. Slices, which have a size determined at runtime, are covered later. • 请尝试访问出界数组元素。系统会在运行时检查数组访问。Rust 通常会通过优化消除这些检查，以 segment should take about 55 minutes.

This allows us to perform computation on slices of different sizes. • Slices always borrow from another object. In this example, a has to remain 'alive' (in scope)
