Function bitvec::ptr::bitslice_from_raw_parts_mut[−][src]

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

Performs the same functionality as bitslice_from_raw_parts, except that a raw mutable bit-slice is returned, as opposed to a raw immutable bit-slice.

See the documentation of bitslice_from_raw_parts for more details.

This function is safe, but actually using the return value is unsafe. See the documentation of slice::from_raw_parts_mut for bit-slice safety requirements.

ptr::slice_from_raw_parts

Examples

use bitvec::ptr;
use bitvec::order::Lsb0;

let mut x = [5u8, 10, 15];
let bitptr = ptr::BitPtr::<_, Lsb0, _>::from_mut(&mut x[0]);
let bitslice = ptr::bitslice_from_raw_parts_mut(bitptr, 24);
unsafe { &mut *bitslice }.set(0, true);
assert!(unsafe { &*bitslice }[0]);
