Hi, thanks for the contribution. I am pretty sure a simpler solution to that problem would be to provide the `Iterator` with a size hint, this should give compiler enough information to generate code identical to yours. You can try doing that instead, here is example of that optimization being applied for an `Vec<T>`: https://godbolt.org/z/4erhYsxsG The clue is those two lines ```asm mov rdi, qword ptr [rbx + 8] mov rbx, qword ptr [rdi + 8*rax - 8] // Load the ptr + (len - 1) ``` -- This is an automated message from the Apache Git Service.
