Variable std.typecons.Tuple.expand
Use t
for a Tuple
t
to expand it into its
components. The result of expand
acts as if the Tuple
's components
were listed as a list of values. (Ordinarily, a Tuple
acts as a
single value.)
Example
auto t1 = tuple(1, " hello ", 'a');
writeln(t1 .toString()); // `Tuple!(int, string, char)(1, " hello ", 'a')`
void takeSeveralTypes(int n, string s, bool b)
{
assert(n == 4 && s == "test" && b == false);
}
auto t2 = tuple(4, "test", false);
//t.expand acting as a list of values
takeSeveralTypes(t2 .expand);
