Could anybody explain what's Outstream doing here,and what does DString(Outstream) mean?

Thanks in advance.

I'm learning c3, too. This might be wrong, but...

What is OutStream

Outstream is an interface in std::io::stream:

//Line 19 - 27
interface OutStream
{
	fn void? destroy() @optional;
	fn void? close() @optional;
	fn void? flush() @optional;
	fn usz? write(char[] bytes);
	fn void? write_byte(char c);
	fn usz? read_to(InStream in) @optional;
}

In this page, you may found this:

To declare that a type implements an interface, add it after the type name.

What DString(Outstream) mean

DString is a type, it just implemented OutStream interface.
