# Bit-Slice Pointer Construction
This forms a raw [`BitSlice`] pointer from a bit-pointer and a length.
## Original
[`ptr::slice_from_raw_parts`](core::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.
```rust
use bitvec::{
prelude::*,
index::BitIdx,
ptr as bv_ptr,
};
let data = 6u16;
let head = BitIdx::new(1).unwrap();
let ptr = BitPtr::<_, _, Lsb0>::new((&data).into(), head).unwrap();
let slice = bv_ptr::bitslice_from_raw_parts(ptr, 10);
let slice_ref = unsafe { &*slice };
assert_eq!(slice_ref.len(), 10);
assert_eq!(slice_ref, bits![1, 1, 0, 0, 0, 0, 0, 0, 0, 0]);
```
