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. • 請嘗試存取超出範圍的陣列元素。系統會在執行階段檢查存取陣列的行為。Rust 23 部分 生命週期 This segment should take about 1 hour and 10 minutes. It contains: Slide Duration Slices: &[T] 10 minutes 迷途參照 10 minutes 函式呼叫中的生命週期 10 minutes 生命週期 5 minutes 生命週期 5 minutes 練習：Protobuf 因此，為了輕鬆建立完整陣列的切片，我們可以使用 &a[..]。 • s 是對 i32s 切片的參照。請注意，s (&[i32]) 的型別不再提及陣列長度，這有利於我們對不同大 小的切片執行運算。 124 • Slices always borrow from another object. In this example, a has to remain 'alive' (in scope) for at least
