I have a used a template, because I cannot directly use the

either, so is there another parameter type I can use, such that
I can have the concept of an abstract stream of bytes.
With the help of a template constraint you can abstract this. It
looks like your problem is more getting the whole range since
.byLine or .byChunk don't return the full stuff. Maybe use
std.alsorithm.joiner. As you noted you can carry the iterator
without knowing the type with auto, example:
---
import std.stdio;
import std.range, std.algorithm;
void main(string[] args)
{
auto inputRange = File(__FILE__).byChunk(1024).joiner;
Foo foo = Foo(inputRange);
}
struct Foo
{
this(T)(T t)
if (isInputRange!T && is(ElementType!T == ubyte))
{
foreach(byte b; t)
{
writef("0x%.2X ", b);
if (b == 0xA) writeln;
}
}
}
