Type tags are used to select variants of a member, function, template or constructor. A Type tag always has only a single value which is passed wherever a parameter of that tag's type is needed.
The argument which expects a type-tag value will always be declared in such a way, that it is optional. Examples of type tag use are:
Of course, this only works with objects which explicitly declare, that they take an optional senf::NoThrow_t type parameter.
| enum senf::NoInit_t |
Type tag selecting uninitialized variant of something.
This tag is used to select the unititialized variant of a member, function, template or constructor (mostly a constructor). An argument of this type is always declared in such a way, that it is optional.
There is only a single value for this type: senf::noinit which is the value to pass wherever an (optional) senf::NoInit_t parameter is requested.
