如果前提条件在运行时失败,该函数将输出一条错误消息并终止程序。
如果常量表达式中的前提条件失败,则会导致编译时错误。
我希望当断言在常量计算表达式中失败时,该函数也会生成编译时错误:
const int a = (Assert(false),0); //generate a runtime error
//=> I would like it generates a compile time error

我考虑过使用std::is_constant_evaluated:compiler-explorer
#include <type_traits>
using namespace std;
void runtime_error();
constexpr void compile_time_error(){} //should generates a compile time error
constexpr void Assert(bool value){
if (value) return;
if (is_constant_evaluated())
compile_time_error();
else
runtime_error();
}

我只使用 GCC,我寻找了一个会导致编译时错误的内置函数,该函数是 constexpr,但没有找到。
是否有任何技巧可以在可以常量求值的表达式中获得编译时错误?
我有两个(我希望)等效的功能,例如:
fn slow_summary(foo: &Foo) -> Bar
fn fast_summary(foo: Foo) -> Bar
Run Code Online (Sandbox Code Playgroud)
我想在调用站点添加一个 debug_assert 语句,快速摘要给出与慢速摘要相同的结果。例如。
fn bar(foo: Foo) -> Baz {
let summary = fast_summary(foo);
debug_assert_eq!(summary, slow_summary(&foo));
baz(summary)
}

但是我不能这样做,因为foo已经被调用fast_summary(Foo不是Cloneor 的一个实例Copy。我可以让它Clone然后clone它但仍然引入不必要的运行时债务并且也使代码看起来更丑陋)。理想情况下,我会slow_summary 先打电话。而再打电话fast_summary,但我要如何做到这一点,同时还确保slow_summary当调试断言导通时才叫什么名字?

myMethod('start', Object{5})
我知道该对象有一个键,segmentB-> 当控制台将其记录在存根中时,我看到它,但我不想开始在存根中进行断言
我想断言,segmentB 的值以'MPI_'
我虽然将“应该通过匹配来调用”和 Cypress.sinon 断言结合起来,如下所示,但它不起作用。

.should('beCalledWithMatch', 'start')或在没有可变部分的情况下断言对象的键/值对是可行的,但我很感激使用正则表达式进行断言的任何帮助。
