I see. Are you not concerned by the fact that with this API, the input stream has to perform heap allocation when its internal buffer is full because the delegate could always ask for some more characters. That prevents the possibility to make a reading mecanisme that does not allocate anything on the stack. >> One last point: any comments about using writeTo with my "stream" API >> like readFrom ? > > I think this is what writeTo (as proposed) already does. the proposed writeTo is: writeTo(void delegate(const(char)[]) sink, in char[] format). Here, the writeTo method writes the character in its own buffer, then gives it to sink. A writeTo with a "stream API" would be: writeTo(char[] delegate(size_t) stream, in char[] format). Here stream provides a buffer, and writeTo has to use this buffer, then tell how much buffer it used to stream. I'm not sure mine is better, I'm just asking. -- Christophe
