Lets say I have the following struct:
const test_struct: type = struct { a: []u8, };
I want to have something like this:
const arr = [_]test_struct{ .{ .a = "a" }, .{ .a = "b" } };
I dont care to mutate any of the data (would also like to know how I would go about this if I wanted the data to be mutable).
How do I do this?

If you don't need to mutate any of that data, use []const u8 instead.
If you want it to be mutable though, then you ultimately need to decide where the memory is going to live.
If on the stack, you want var buf: [32]u8 = undefined; and then use &buf or buf[0..n] will yield a []u8.
Otherwise, you'd need to use an allocator.
You could also make buf a global variable instead of on the stack, and that would work for mutable too - but that's generally not what you want.
