Sorry, it seems I completely misunderstood you goal. I thought
that take() consumed its input (which mostly only shows that I
really am careful about not reusing ranges). Writting a take
that consume shouldn't be difficult though:
import std.range, std.traits;
Take!R takeConsume(R)(auto ref R input, size_t n)
if (isInputRange!(Unqual!R)
&& !isInfinite!(Unqual!R)
{
auto buffer = input.take(n);
input = input.drop(buffer.walkLength);
return buffer;
}
but I think going with std.bitmanip/read may be the easiest in
the end.
Turns out bitmanip is actually using a loop.
foreach(ref e; bytes)
{
e = range.front;
range.popFront();
}
By the way, in your code above you are actually reusing the
range: take is followed by drop and it won't work on an input
range like 'byChunk'. That's the problem I ran into (see first
post).
