Today I've made an abortive attempt at replacing my code's [1]
dependence on unstd.multidimarray [2] with ndslice.
I'm guessing it's just me being stupid, but could anyone supply
with some hints on how to do the conversion with a minimum of
fuss?
Basically I have an N-dimensional array (N is known at compile
time) of type T wrapped in a struct to carry some additional
information.
I then address it using size_t[N] fixed-size arrays, and loop
over it a lot with foreach, which also uses size_t[N] as index.
So it looks something like this:
struct Field(T, uint N) {
alias arr this;
MultidimArray!(T, N) arr; // is there any way to supply the
correct type here with ndslice? I cannot use auto, right?
this (in size_t[N] lengths) {
arr = multidimArray!T(lengths);
}
}
and then things like
foreach(immutable p, ref pop; someField) {
pop = foo(someOtherField[bar(p)]);
...
}
where p is of type size_t[N].
I tried using ndarray in conjunction with the
std.experimental.allocator, but I don't particularly care about
memory management;
these are large arrays that are allocated once and kept around
for the duration of the program.
Any help would be appreciated.
