Enumerator#next

() -> E

e.next → object

static VALUE
enumerator_next(VALUE obj)
{
    VALUE vs = enumerator_next_values(obj);
    return ary2sv(vs, 0);
}

Returns the next object in the enumerator, and move the internal position forward. When the position reached at the end, StopIteration is raised.

a = [1,2,3]
e = a.to_enum
p e.next   #=> 1
p e.next   #=> 2
p e.next   #=> 3
p e.next   #raises StopIteration
