Yet another Mock framework Callista

then after implementing 1229 I got at least warning during compile time. Assertions to ensure correct assumptions about constants, types, and more. All checks provided by this crate are performed at compile-time. This allows for static_assert(e,"Static error in foo!

Expression (including pointers) that evaluates to nonzero (TRUE) or 0 (FALSE). C++11 added another type of assert called static_assert. A static_assert is an assertion that is checked at compile-time rather than at runtime, with a failing static_assert causing a compile error. A static_assert takes the following form: C++11 introduces this new type of assertion which checks an expression at compile time. This is different from regular “assert” statement, which works at runtime.

If the condition results as 1 or true, the static_assert declaration has no effect. _Static_assert(FOO_VERSION >= 2, "foo version 2+ required"); Static assertions can also be used in combination with the new _Alignof operator and generic selection mechanism to enforce alignment and type constraints at compile-time: A static_assert() has a mandatory first parameter, the condition, that is a bool constexpr. It might have a second parameter, the message, that is a string literal.

However unlike local variables that get created and destroyed every time a function is called, static variables persist beyond the function call, preserving their data between function calls. 次の例は、無効な定数式を指定した static_assert 宣言の使用について示しています。 static_assert(1 / 0, "never shows up!"); このプログラムをコンパイルすると、コンパイラーは static_assert 宣言のストリング・リテラルを表示しません。 Library implementation of so-called `static_assert` as a macro - nodakai/rust-static_assert_macro www.msdn.microsoft.com at the beginning of the code, before the inclusion of .

How to test static_assert? - Roland Bock - Meeting C++ 2016Slides: https://meetingcpp.com/index.php/tv16/items/8.html Example 3: The following example shows the use of a _Static_assert declaration with an invalid constant expression. _Static_assert(1 / 0, "never shows up!"); When you compile this program, the compiler does not show the string literal in the _Static_assert declaration. Assert assert(a != 1); This is a macro that implements a runtime assertion, which can be used to verify assumptions made by the program and print a diagnostic message if this assumption is false..
