Every function described in [rand.adapt]
that has a function parameter q of type Sseq&
for a template type parameter named Sseq
that is different from type seed_seq
throws what and when the invocation of q.generate throws.
Descriptions are provided in [rand.adapt]
only for adaptor operations
that are not described in subclause [rand.req.adapt]
or for operations where there is additional semantic information.
In particular,
declarations for copy constructors,
for copy assignment operators,
for streaming operators,
and for equality and inequality operators
are not shown in the synopses.
