allTuple

Detect whether all elements of a generic tuple A satisfy the predicate pred.

Returns true for an empty tuple.

template allTuple (

alias pred

A...

) {

alias predTemplate = unaryPred!pred;

static if(A.length == 0)

static if(!(A.length == 0))

static if(predTemplate!(A[0]))

static if(!(A.length == 0))

static if(!(predTemplate!(A[0])))

}
