Function bitslice_from_raw_parts_mut

pub fn bitslice_from_raw_parts_mut<T, O>(
    ptr: BitPtr<Mut, T, O>,
    len: usize,
) -> *mut BitSlice<T, O>
where
    T: BitStore,
    O: BitOrder,

Bit-Slice Pointer Construction

This forms a raw BitSlice pointer from a bit-pointer and a length.

Original

ptr::slice_from_raw_parts

Examples

You will need to construct a BitPtr first; these are typically produced by existing BitSlice views, or you can do so manually.

use bitvec::{
  prelude::*,
  index::BitIdx,
  ptr as bv_ptr,
};

let mut data = 6u16;
let head = BitIdx::new(1).unwrap();
let ptr = BitPtr::<_, _, Lsb0>::new((&mut data).into(), head).unwrap();
let slice = bv_ptr::bitslice_from_raw_parts_mut(ptr, 10);
let slice_ref = unsafe { &mut *slice };
assert_eq!(slice_ref.len(), 10);
slice_ref.set(2, true);
assert_eq!(slice_ref, bits![1, 1, 1, 0, 0, 0, 0, 0, 0, 0]);
