I have the following function signature:
fn medianCut(
allocator: std.mem.Allocator,
partitions: std.ArrayList([]u32),
pixels: []u32,
depth: u8,
) !void { .... }
Inside this function, I do: partitions.append(...).
And even though the parameter type is clearly non-cost, I get an error saying:
sick harness
partitions needs to be a *std.ArrayList([]u32)
function parameters are always const in zig

Thanks, If I do that, I get an error at the call site:
Even though the call is straightforward:
var partitions = std.ArrayList([]u32).init(allocator);
defer partitions.deinit(allocator);
try medianCut(allocator, &partitions, pixels, 2);
Yep!

Even though the call is straightforward:
```rs
var partitions = std.ArrayL...
is this pseudo code or exactly what it actually is?

Exactly what it is
sick harness
does medianCut do recursion?
lapis pecan
Yep!
sick harness
are you passing the address of the arraylist inside medianCut? if so thats the problem
sick harness
partitions is already a pointer inside the function
lapis pecan
yes you were right
sick harness
how did you guess that xD
because i couldnt think of a single other thing lol
