isCopyConstructorEnabled

Template to determine if hook enables or disables copy constructor.

It is enabled by default.

See hasOnUnchecked handler, which can be used in combination with disabled copy constructor to enforce that the result is checked.

If copy constructor is disabled, it severely limits function chaining as Expected needs to be passed as rvalue in that case.

template isCopyConstructorEnabled (

Hook

) {

static if(__traits(hasMember, Hook, "enableCopyConstructor"))

enum isCopyConstructorEnabled;

static if(!(__traits(hasMember, Hook, "enableCopyConstructor")))

enum isCopyConstructorEnabled;

}
