Currently not possible. Enhancement request perhaps?
Looking at the implementation, setting its 'offset' member seems to
work. Based on example from documentation:
import std.outbuffer;
void main() {
OutBuffer b = new OutBuffer();
b.writefln("a%sb", 16);
assert(b.toString() == "a16b\n");
b.offset = 0;
b.writefln("a%sb", 16);
assert(b.toString() == "a16b\n");
}
Bug report perhaps? :)
