using | type = Op< Args... > |
A specialization of the general template.
The trick this class uses is that, just like the general template, its second argument is always void
, but here it is written as void_t<Op<Args...>>
and consequently the compiler will only select this specialization if Op<Args...>
is in fact a valid type. This means that the operation we seek to understand is indeed supported.
This specialization then declares member variables and types according to the successful detection.
