2016-11-03 · This talk will demonstrate several options for testing static_assert, ranging from the build system, over the compiler features to template meta programming.

Static Semantics. 10/2. A pragma Assertion_Policy is a configuration pragma that specifies the assertion policy in effect for the compilation units to which it

Syntax: static_assert( constant_expression, string_literal ); Parameters: constant_expression: An integral constant expression that can be converted to a Boolean. Unlike _Static_assert, the second parameter needs to be a proper token name so that a variable name can be created with it. If the assertion fails, the variable name is seen in the compiler error, since that variable was used in a syntactically incorrect array declaration. 2020-04-10 · This page was last modified on 10 April 2020, at 06:00.

If the condition results as 1 or true, the static_assert declaration has no effect. http://stackoverflow.com/questions/14621968/how-to-do-static-assert-with-macros.

Note that if you're compiling in C89 mode, you will only be able to perform static … Q #2) What is static_assert?

_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:

const NUM : usize = 32 ; const_assert ! static_assert is a compiler directive. It allows you to check type information at compile time.

If size and capacity are member variables, then the compiler does not know their values are at compile time. The declaration of static assertions does not declare a new type or object, and does not imply any size or time cost at run time. The C++ programming language also supports the _Static_assert keyword in all language levels for improved compatibility with the C programming language. static_assert:这个宏用于检测和诊断编译时错误。编译期，这是一个与 CRT-assert（运行时宏）相反的宏。这个好东西用于检测编译时程序的不变量。 A static_assert-declaration takes the following form: static_assert ( constant-expression , string-literal ) ; Intuitively, a static_assert-declaration may appear anywhere that a using-declaration can, including namespace scope, block scope, and class member declaration lists. If static_assert is going to be in the next C++, and possibly in the next C, naming one's macro the same virtually guarantees incompatibility with these upcoming standards.

Static assert is used to make assertions at compile time. When the static assertion fails, the program simply doesn't compile.
