有兩個主要的「設定檔」可產生程式碼，分別是「Debug」(加強執行階段檢查，最佳化程度較低) 和「Release」(減少執行階段檢查，大規模最佳化)。這些設定檔位於頂端的「Debug」下方。 • 感興趣的話，不妨點選「...」下的「ASM」查看產生的組語程式碼。 學員準備休息時，請鼓勵他們開啟 Playground 略微試驗一下。在剩餘的課堂時間，建議他們持續開啟 Playground 分頁嘗試操作。如果學生程度較高，想進一步瞭解 S。 53.2 行內組語 有時候，我們需要使用組語，才能執行 Rust 程式碼無法執行的作業。舉例來說，如要發出 HVC (管理程序 呼叫) 指示韌體關閉系統： use core::arch::asm; use core::panic::PanicInfo; mod exceptions; const PSCI_SYSTEM_OFF: u32 = 0x84000008; extern "C" Safe because this only uses the declared registers and doesn't do // anything with memory. unsafe { asm!("hvc #0", inout("w0") PSCI_SYSTEM_OFF => _, inout("w1") 0 => _, inout("w2") 0 => _, inout("w3") 0
