std::meta::is_explicit

consteval bool is_explicit( std::meta::info r );

Returns true if r represents an explicit constructor or conversion function. Otherwise returns false.

Parameters

Return value

true if r represents a member function that is declared explicit; otherwise false.

Notes

If r does not represent a function, the result is false. In particular, the result is false if r represents a function template.

Example

#include <meta>

struct A
{
    explicit operator bool() const;

    template<class T>
    explicit(^^T == ^^void) operator T*() const;
};

static_assert(std::meta::is_explicit(^^A::operator bool));
static_assert(std::meta::is_explicit(^^A::operator void*));
static_assert(!std::meta::is_explicit(^^A::operator int*));
