Expand description

§Single-Bit Unaligned Read

This reads the bit out of src directly. It uses compiler intrinsics to tolerate an unaligned T address. However, because BitPtr has a type invariant that addresses are always well-aligned (and non-null), this has no benefit or purpose.

§Original

ptr::read_unaligned

§Safety

Because this performs a dereference of memory, it inherits the original ptr::read_unaligned’s requirements:

  • src must be valid to read.
  • src must point to an initialized value of T.

§Examples

use bitvec::prelude::*;
use bitvec::ptr as bv_ptr;


let data = 128u8;
let ptr = BitPtr::<_, _, Msb0>::from_ref(&data);
assert!(unsafe { bv_ptr::read_unaligned(ptr) });
