Function try_cast_slice_rc

pub fn try_cast_slice_rc<A, B>(
    input: Rc<[A]>,
) -> Result<Rc<[B]>, (PodCastError, Rc<[A]>)> 
where
    A: NoUninit + AnyBitPattern,
    B: NoUninit + AnyBitPattern,

Available on crate feature dep_bytemuck only.

Attempts to cast the content type of a Rc<[T]>.

On failure you get back an error along with the starting Rc<[T]>.

The bounds on this function are the same as cast_mut, because a user could call Rc::get_unchecked_mut on the output, which could be observable in the input.

Failure

• The start and end content type of the Rc<[T]> must have the exact same alignment.
• The start and end content size in bytes of the Rc<[T]> must be the exact same.
