Hello,
I'm writing a small parser for a specific binary format. The
format is parsed by way of a sequence of functions, each
deserializing a small portion of the format into a D type such as
int, double, string, etc., operating on a single InputRange. The
problem is, if I pass a slice to each of these functions, the
slice doesn't get mutated by the popFront function used in the
functions, so something like this:
ubyte[] slice;
...
int a = readInt(slice);
double b = readDouble(slice);
Ends up failing, because readInt properly reads an int, but the
slice is not mutated "outside" of itself, which means readDouble
will not read from where readInt stopped, and instead read from
the start of the slice, and failing because there is an int
encoded there and not a double. Both functions' signatures are
like this:
T readXXX(Range)(auto ref Range range) if (isInputRange!Range)
So my question is, is there a way to treat a slice strictly as an
InputRange, so that it is mutated no matter what? Or is there
another way to do what I'm trying to do?
I've worked around it using a "wrapper" InputRange struct, but I
feel like there must be another way.
Thanks!
