When it comes to compile-time polymorphism or duck typing, they are both
RandomAccessRanges. (Pedantically, [1, 2, 3] is not a range (I think
:P), but a container. Although, any slice of it is a RandomAccessRange.)
import std.range;
import std.stdio;
void foo(R)(R r)
if (isRandomAccessRange!R)
{
if (!r.empty) {
writeln(r[0]);
}
}
void main()
{
foo([1, 2, 3]);
foo(iota(2, 10));
}
When it comes to runtime polymorphism, they can be both
RandomAccessFinite!int:
import std.range;
import std.stdio;
void foo(RandomAccessFinite!int r)
{
if (!r.empty) {
writeln(r[0]);
}
}
void main()
{
RandomAccessFinite!int r;
r = inputRangeObject([1, 2, 3]);
foo(r);
r = inputRangeObject(iota(2, 10));
foo(r);
}
