How do I allocate a Vec<u8> that is aligned to the size of the cache line?
hope this fix your issue You can enforce the alignment of a type to a certain size using [repr(align(...))]. We also use repr(C) to ensure that this type has the same memory layout as an array of bytes.You can then create a vector of the aligned type

Why can I not mutably borrow separate fields from a mutex guard?
should help you out Mutex::lock returns a RAII lock guard in addition of ways to deal with its contained value. To get its contained value as mut (and subsequently "split borrow"), you need to: save the guard (returned by lock) in a separate value, a

Rust - why it does not give me an error when borrowed &mut twice

How can I simplify repeating function logic
fixed the issue. Will look into that further You could change same_line into line_ending. Instead of storing true, you would store \n and always use print!("... {}", ..., self.line_ending). I would also add a function pop_line_ending() which returns
