xtd::post_incrementable< type_t > Struct Template Reference

Definition

template<typename type_t>
struct xtd::post_incrementable< type_t >

Represents the post decrementable concept.

Definition

concept xtd::post_incrementable = requires(xtd::raw_type<type_t>& a) {{a++} -> std::same_as<xtd::raw_type<type_t>>;}

Header

Examples

The following code shows how to use xtd::post_incrementable concept

#include <xtd/xtd>
 
auto print_is_post_incrementable(auto value) noexcept {
  println("{} ({}) {} post_incrementable", value, type_of(value), post_incrementable<decltype(value)> ? "is" : "is not");
}
 
auto main() -> int {
  print_is_post_incrementable(42);
  print_is_post_incrementable(time_span {1, 2, 3});
  print_is_post_incrementable(version {1, 2, 3});
}
 
// This code produces the following output :
//
// 42 (int) is post_incrementable
// 01:02:03 (xtd::time_span) is post_incrementable
// 1.2.3 (xtd::version) is not post_incrementable
